Ssedheq, the Hebrew root for righteousness, had, like the Latin "rectus," in its earliest and now almost forgotten uses, a physical meaning. This may have been either straightness, or more probably soundness,—the state in which a thing is all right.[127] Paths of righteousness, in Psalm xxiii., ver. 4, are not necessarily straight paths, but rather sure, genuine, safe paths.[128] Like all physical metaphors, like our own words "straight" and "right," the applicability of the term to moral conduct was exceedingly elastic. It has been attempted to gather most of its meaning under the definition of conformity to norm;[129] and so many are the instances in which the word has a forensic force,[130] as of vindication or justification, that some have claimed this for its original, or, at least, its governing sense. But it is improbable that either of these definitions conveys the simplest or most general sense of the word. Even if conformity or justification were ever the prevailing sense of ssedheq, there are a number of instances in which its meaning far overflows the limits of such definitions. Every one can see how a word, which may generally be used to express an abstract idea, like conformity, or a formal relation towards a law or person, like justification, might come to be applied to the actual virtues, which realise that idea or lift a character into that relation. Thus righteousness might mean justice, or truth, or almsgiving, or religious obedience,—to each of which, in fact, the Hebrew word was at various times specially applied. Or righteousness might mean virtue in general, virtue apart from all consideration of law or duty whatsoever. In the prophet Amos, for instance, righteousness is applied to a goodness so natural and spontaneous that no one could think of it for a moment as conformity to norm or fulfilment of law.[131]

In short, it is impossible to give a definition of the Hebrew word, which our version renders as righteousness, less wide than our English word right. Righteousness is right in all its senses,—natural, legal, personal, religious. It is to be all right, to be right-hearted, to be consistent, to be thorough; but also to be in the right, to be justified, to be vindicated; and, in particular, it may mean to be humane (as with Amos), to be just (as with Isaiah), to be correct or true to fact (as sometimes with our own prophet), to fulfil the ordinances of religion, and especially the command about almsgiving (as with the later Jews).

Let us now keep in mind that righteousness could express a relation, or a general quality of character, or some particular virtue. For we shall find traces of all these meanings in our prophet's application of the term to Israel and to God.

II. The Righteousness of Israel.

One of the simplest forms of the use of righteousness in the Old Testament is when it is employed in the case of ordinary quarrels between two persons; in which for one of them to be righteous means to be right or in the right.[132] Now to the Hebrew all life and religion was based upon covenants between two,—between man and man and between man and God. Righteousness meant fidelity to the terms of those covenants. The positive contents of the word in any single instance of its use would, therefore, depend on the faithfulness and delicacy of conscience by which those terms were interpreted. In early Israel this conscience was not so keen as it afterwards came to be, and accordingly Israel's sense of their righteousness towards God was, to begin with, a comparatively shallow one. When a Psalmist asseverates his righteousness and pleads it as the ground for God rewarding him, it is plain that he is able with sincerity to make a claim, so repellent to a Christian's feeling, just because he has not anything like a Christian's conscience of what God demands from man. As Calvin says on Psalm xviii., ver. 20, "David here represents God as the President of an athletic contest, who had chosen him as one of His champions, and David knows that so long as he keeps to the rules of the contest, so long will God defend him." It is evident that in such an assertion righteousness cannot mean perfect innocence, but simply the good conscience of a man, who, with simple ideas of what is demanded from him, feels that on the whole "he has" (slightly to paraphrase Calvin) "played fair."

Two things, almost simultaneously, shook Israel out of this primitive and naïve self-righteousness. History went against them, and the prophets quickened their conscience.[133] The effect of the former of these two causes will be clear to us, if we recollect the judicial element in the Hebrew righteousness,—that it often meant not so much to be right, as to be vindicated or declared right. History, to Israel, was God's supreme tribunal. It was the faith of the people, expressed over and over again in the Old Testament, that the godly man is vindicated or justified by his prosperity: the way of the ungodly shall perish. And Israel felt themselves to be in the right, just as David, in Psalm xviii., felt himself, because God had accredited them with success and victory. But when the decision of history went against the nation, when they were threatened with expulsion from their land and with extinction as a people, that just meant that the Supreme Judge of men was giving His sentence against them. Israel had broken the terms of the Covenant. They had lost their right; they were no longer righteous. The keener conscience, developed by prophecy, swiftly explained this sentence of history. This declaration, that the people were unrighteous, was due, the prophet said, to the people's sins. Isaiah not only exclaimed, Your country is desolate, your cities are burned with fire; he added, in equal indictment, How is the faithful city become an harlot! it was full of justice, righteousness lodged in it, but now murderers: thy princes are rebellious, they judge not the fatherless, neither doth the cause of the widow come before them. To Isaiah and the earlier prophets Israel was unrighteous because it was so immoral. With their strong social conscience, righteousness meant to these prophets the practice of civic virtues,—truth-telling, honesty between citizens, tenderness to the poor, inflexible justice in high places.

Here then we have two possible meanings for Israel's righteousness in the prophetic writings, allied and necessary to one another, yet logically distinct,—the one a becoming righteous through the exercise of virtue, the other a being shown to be righteous by the voice of history. In the one case righteousness is the practical result of the working of the Spirit of God; in the other it is vindication, or justification, by the Providence of God. Isaiah and the earlier prophets, while the sentence of history was still not executed and might through the mercy of God be revoked, incline to employ righteousness predominantly in the former sense. But it will be understood how, after the Exile, it was the latter, which became the prevailing determination of the word. By that great disaster God finally uttered the clear sentence, of which previous history had been but the foreboding. Israel in exile was fully declared to be in the wrong—to be unrighteous. As a church, she lay under the ban; as a nation, she was discredited before the nations of the world. And her one longing, hope and effort during the weary years of Captivity was to have her right vindicated again, was to be restored to right relations to God and to the world, under the Covenant.

This is the predominant meaning of the term, as applied to Israel, in Isa. xl.-lxvi. Israel's unrighteousness is her state of discredit and disgrace under the hands of God; her righteousness, which she hopes for, is her restoral to her station and destiny as the elect people. To our Christian habit of thinking, it is very natural to read the frequent and splendid phrases, in which righteousness is attributed or promised to the people of God in this evangelical prophecy, as if righteousness were that inward assurance and justification from an evil conscience, which, as we are taught by the New Testament, is provided for us through the death of Christ, and inwardly sealed to us by the Holy Ghost, irrespective of the course of our outward fortune. But if we read that meaning into righteousness in Isa. xl.-lxvi., we shall simply not understand some of the grandest passages of the prophecy. We must clearly keep in view, that while the prophet ceaselessly emphasizes the pardon of God spoken home to the heart of the people, as the first step towards their restoral, he does not apply the term righteousness to this inward justification,[134] but to the outward vindication and accrediting of Israel by God before the whole world, in their redemption from Captivity, and their reinstatement as His people. This is very clear from the way in which righteousness is coupled with salvation by the prophet, as (lxii. 1): I will not rest till her righteousness go forth as brightness, and her salvation as a lamp that burneth. Or again from the way in which righteousness and glory are put in parallel (lxii. 2): And the nations shall see thy righteousness, and all kings thy glory. Or again in the way that righteousness and renown are identified (lxi. 11): The Lord Jehovah will cause righteousness and renown to spring forth before all the nations. In each of these promises the idea of an external and manifest splendour is evident; not the inward peace of justification felt only by the conscience to which it has been granted, but the outward historical victory appreciable by the gross sense of the heathen. Of course the outward implies the inward,—this historical triumph is the crown of a religious process, the result of forgiveness and a long purification,—but while in the New Testament it is these which would be most readily called a people's righteousness, it is the former (what the New Testament would rather call the crown of life), which has appropriated the name in Isa. xl.-lxvi. The same is manifest from another text (xlviii. 18): O that thou hadst hearkened to My commandments; then had thy peace been as the River, and thy righteousness like the waves of the sea. Here righteousness is not only not applied to inward morality, but set over against this as its external reward,—the health and splendour which a good conscience produces. It is in the same external sense that the prophet talks of the robe of righteousness with its bridal splendour, and compares it to the appearance of Spring (lxi. 10-11).

For this kind of righteousness, this vindication by God before the world, Israel waited throughout the Exile. God addresses them as they that pursue righteousness, that seek Jehovah (li. 1). And it is a closely allied meaning, though perhaps with a more inward application, when the people are represented as praying God to give them ordinances of righteousness (lviii. 2),—that is, to prescribe such a ritual as will expiate their guilt and bring them into a right relation with Him. They sought in vain. The great lesson of the Exile was that not by works and performances, but through simply waiting upon the Lord, their righteousness should shine forth. Even this outward kind of justification was to be by faith.

The other meaning of righteousness, however,—the sense of social and civic morality, which was its usual sense with the earlier prophets,—is not altogether excluded from the use of the word in Isa. xl.-lxvi. Here are some commands and reproaches which seem to imply it. Keep judgement, and do righteousness,—where, from what follows, righteousness evidently means observing the Sabbath and doing no evil (lvi. 1 ff). And justice is fallen away backward, and righteousness standeth afar off, for truth is fallen in the street, and steadfastness cannot enter (lix. 14). These must be terms for human virtues, for shortly afterwards it is said: Jehovah was displeased because there was no justice. Again, They seek Me as a nation that did righteousness (lviii. 2); Hearken unto Me, ye that know righteousness, a people—My law is in their hearts (li. 7); Thou meetest him that worketh righteousness (lxiv. 5); No one sues in righteousness, and none goeth to law in truth (lix. 4). In all these passages righteousness means something that man can know and do, his conscience and his duty, and is rightly to be distinguished from those others, in which righteousness is equivalent to the salvation, the glory, the peace, which only God's power can bring. If the passages, that employ righteousness in the sense of moral or religious observance, really date from the Exile, then the interesting fact is assured to us that the Jews enjoyed some degree of social independence and responsibility during their Captivity. But it is a very striking fact that these passages all belong to chapters, the exilic origin of which is questioned even by critics, who assign the rest of Isa. xl.-lxvi. to the Exile. Yet, even if these passages have all to be assigned to the Exile, how few they are in number! How they contrast with the frequency, with which, in the earlier part of this book,—in the orations addressed by Isaiah to his own times, when Israel was still an independent state,—righteousness is reiterated as the daily, practical duty of men, as justice, truthfulness and charity between man and man! The extreme rarity of such inculcations in Isa. xl.-lxvi. warns us that we must not expect to find here the same practical and political interest, which formed so much of the charm and the force of Isa. i.-xxxix. The nation has now no politics, almost no social morals. Israel are not citizens working out their own salvation in the market, the camp and the senate; but captives waiting a deliverance in God's time, which no act of theirs can hasten. It is not in the street that the interest of Second Isaiah lies: it is on the horizon. Hence the vague feeling of a distant splendour, which, as the reader passes from ch. xxxix. to ch. xl., replaces in his mind the stir of living in a busy crowd, the close and throbbing sense of the civic conscience, the voice of statesmen, the clash of the weapons of war. There is no opportunity for individuals to reveal themselves. It is a nation waiting, indistinguishable in shadow, whose outlines only we see. It is no longer the thrilling practical cry, which sends men into the arenas of social life with every sinew in them strung: Learn to do well; seek justice, relieve the oppressed, judge the fatherless, plead for the widow. It is rather the cry of one who still waits for his working day to dawn: I will lift up mine eyes to the hills, from whence cometh my help? Righteousness is not the near and daily duty, it is the far-off peace and splendour of skies, that have scarce begun to redden to the day.
