7. The scriptural parables have a rich variety of form, sometimes approaching to that of the allegory, when the interpretation must be upon the same general principle. In its pure form, however, the parable does not, like the allegory, represent directly the higher spiritual truth, but is simply a narrative to illustrate it. It may be introduced in the absolute form, like the parable of the barren fig-tree (Luke 13:6-9); or, more commonly, in the shape of a similitude, thus: "The kingdom of heaven is likened unto a man which sowed good seed in his field" (Matt. 13:24); "Whereunto shall we liken the kingdom of God? or with what comparison shall we compare it?" Mark 4:30. It may be left without explanation, but more commonly an explanatory remark is added. So to the parable of the two sons whom the father asked to work in his vineyard is added the application: "Verily I say unto you, that the publicans and the harlots go into the kingdom of God before you" (Matt. 21:28-31); and the parable of the Pharisee and publican is both introduced and followed by an explanatory clause (Luke 18:9-14). All such clauses are of the highest importance for the interpretation of the parables to which they are annexed. In the interpretation of a parable, the first and most important thing is to ascertain the spiritual truth which it is intended to inculcate. How far a spiritual significance is to be sought for the particular incidents of parables is a question to be determined separately for each, according to its nature.
In the parable of the sower, which our Lord himself interpreted (Matt. 13:3-8, 19-23), all the parts are essential, since the four different kinds of soil represent four different classes of hearers. So in the parable of the tares in the field (Matt. 13:24-30, 37-43), the good seed sown by the owner of the field, the tares sown by his enemy, the separation, at the time of harvest, of the tares from the wheat, the burning of the tares, and the gathering of the wheat into the barn, are all main incidents in its spiritual application. Not so in the parable of the ten virgins (Matt. 25:1-13), of which our Lord himself has given the scope, and, so far as we can see the only scope: "Watch, therefore, for ye know neither the day nor the hour wherein the Son of man cometh." If we go farther, and inquire what is the spiritual meaning of the lamps and oil-vessels, of the equal division of the virgins into five wise and five foolish, of the request of the foolish virgins that the wise would give them oil, and the answer of the wise virgins, we run into useless speculations. All these particulars belong to the drapery of the parable, and are intended to make the story natural and probable.
In the pure form of the parable, the personages introduced to illustrate God's ways of providence and grace do not, as in the allegory, directly represent God himself. It is not necessary, therefore, that there be in all cases a correspondence between their character and that of the holy God. It is sufficient if the words and deeds ascribed to them truly illustrate the spiritual principle in question. In the parable of the unforgiving servant (Matt. 18:23-35), his lord "commanded him to be sold, and his wife and children, and all that he had, and payment to be made" (ver. 25); and afterwards he "was wroth, and delivered him to the tormentors, till he should pay all that was due unto him" (ver. 34). We need not trouble ourselves about the reasonableness of these acts on the part of an earthly lord. It is sufficient for the end of the parable that they were in accordance with the usages of the age, and thus illustrated the great truth which the parable was intended to enforce: "So likewise shall my heavenly Father do also unto you, if ye from your hearts forgive not every one his brother their trespasses" (ver. 35). We have still more forcible illustrations of this principle in such parables as those of the importunate friend (Luke 11:5-8), the unjust judge (Luke 18:1-8), and the unfaithful steward (Luke 16:1-9). The Saviour does not compare God to an indolent friend, who will not arise to accommodate his neighbor with bread till he is forced to do so by his importunity; nor to an unjust judge, who fears not God nor regards men. But he draws illustrations from their conduct of the efficacy of importunate prayer; adding, at the conclusion of each parable, its scope: "And I say unto you, Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you" (Luke 11:9); "And shall not God avenge his own elect, which cry day and night unto him, though he bear long with them?" Luke 18:7. In the parable of the unfaithful steward, our Lord introduces a fraudulent transaction—a transaction so manifestly fraudulent that there is no danger of our thinking that it could have his approbation—that he may thus illustrate the importance of prudent provision for the future. By allowing each of his lord's debtors to diminish the amount due from him, he gains their favor, that in time of need he may be received into their houses. For the right apprehension of the parable, the words of the eighth verse are of primary importance: "And the lord [the master of the steward] commended the unjust steward, because he had done wisely" [prudently, as the Greek word means]. Unjust as the steward's conduct was, he could not but commend it as a prudent transaction for the end which he had in view. Our Saviour adds: "For the children of this world are in their generation [more exactly, towards or in respect to their own generation; that is, in dealing with men of their own sort] wiser than the children of light." The steward and his lord's debtors were all "children of this world," and the transaction between them was conducted upon worldly principles. Our Saviour would have "the children of light"—God's holy children, who live and act in the sphere of heavenly light—provident of their everlasting welfare in the use which they make of this world's goods, as this steward was of his earthly welfare when he should be put out of his stewardship. He accordingly adds, as the scope of the parable (ver. 9): "Make to yourselves friends of [by the right use of] the mammon of unrighteousness [so called as being with unrighteous men the great object of pursuit, and too commonly sought, moreover, by unrighteous means]; that when ye fail [are discharged from your stewardship by death], they may receive you [that is, the friends whom ye have made by bestowing your earthly riches in deeds of love and mercy] into everlasting habitations." Our Lord uses the words, "they may receive you," in allusion to the steward's language: "they may receive me into their houses." They do not receive us by any right or authority of their own, for this belongs to Christ alone; but they receive us in the sense that they bear witness before the throne of Christ to our deeds of love and mercy, by which is manifested the reality of our faith, and thus our title, through grace, to everlasting habitations. Compare the remarkable passage in Matt. 25:34-46, which furnishes a true key to the present parable.
8. To determine whether a symbol is a real transaction or seen only in vision, we must consider both its nature and the context. When Ezekiel, at God's command, visits the temple-court, digs in its wall, and sees the abominations practised there (chap. 8), we know from his own words (ver. 3) that the whole transaction was "in the visions of God." So also the remarkable vision of dry bones. Chap. 37:1-14. But the symbolical action that follows—the joining of two sticks into one—seems to be represented as real; for the people ask concerning it: "Wilt thou not tell us what thou meanest by these?" (ver. 18), and the two sticks are in the prophet's hand "before their eyes" (ver. 20). The nature of the symbolical transaction recorded in Jer. 32:6-12—the purchase of Hanameel's field—with the accompanying historical circumstances, shows that it was real. From the nature of the vision of the chariot of God, on the contrary, which Ezekiel saw (chap. 1:10), as well as from the accompanying notices (chaps. 1:1; 8:1-4), we know that it was represented to the prophet's inner sense, not seen with his outward eyes. The moral character of the transactions recorded by Hosea (chaps. 1-3) has led commentators to decide against their literal occurrence.
In some cases we must remain in doubt whether the symbolical transactions are real or seen in vision. How are we to understand, for example, the transactions recorded in Isa. chap. 20; in Jer. chap. 13:1-11; in Ezek. chap. 4? Concerning such examples expositors will judge differently; but in either way of understanding them, their meaning and the instructions which they furnish are the same.
The subject of symbols will come up again in connection with that of prophecy. At present we consider simply the general principles upon which they are to be interpreted. Here we are to be guided first of all by the writer's own explanations. Where these are wanting we must carefully study the nature of the figures used, and the connections in which they occur.
The sacred writers very commonly indicate the meaning of the symbols which they employ. Thus the prophet Isaiah is directed to loose the sackcloth from his loins, and put off his shoe from his foot, walking naked and barefoot. Chap. 20:2. Then follows the explanation of this symbolical transaction: "Like as my servant Isaiah hath walked naked and barefoot three years for a sign and wonder upon Egypt and Ethiopia; so shall the king of Assyria lead away the Egyptians prisoners, and the Ethiopians captives, young and old, naked and barefoot," etc. (ver. 3, 4). For other examples see the symbol of the girdle (Jer. 13:1-7 compared with ver. 8-11); of the purchase of Hanameel's field (Jer. 32:6-12 compared with ver. 13-15); of the removal of household stuff (Ezek. 12:3-7 compared with ver. 8-12); of the plumb-line (Amos 7:7, 8); of the four horns and four smiths (Zech. 1:18-21); and many other symbolical transactions which will readily occur to the student of Scripture.
But sometimes the symbol is given without an explanation, or with only an obscure intimation of its meaning. The prophet Amos has a vision of grasshoppers, and afterwards of a devouring fire, with only a general intimation that they denote heavy calamities, which the Lord in his pity will avert in answer to prayer. Amos 7:1-6. Here the nature of the symbols, in connection with the known situation of the Israelitish people, shows that they represent the general desolation of the land by foreign enemies. The prophet Ezekiel adds no interpretation to his vision of the Lord enthroned in glory upon the firmament above the chariot with four cherubim and four living wheels full of eyes, in the midst of which a bright fire glows and lightnings blaze. Chaps. 1, 10. From a careful study of the nature of this magnificent imagery we may infer with probability that the cherubim with their wheels, moving every way with the rapidity of a flash of lightning, denote all the agencies and instrumentalities by which God administers his government over the world, which are absolutely at his command, and execute with unerring certainty all his high purposes. The four faces of the cherubim, moreover, which answer to the four principal divisions of living beings among the Hebrews, seem to represent the fulness of their endowments. The meaning of Ezekiel's vision of a New Jerusalem, with its temple and altar, comes more properly under the head of prophecy. Some of the symbols in the book of Zechariah are expounded with beautiful clearness, as that of the two olive-trees. Chap. 4:1-10. Of others the meaning is only hinted at in an enigmatical way; so that their interpretation is a matter of great difficulty and uncertainty. As examples we may refer to the symbol of the ephah (chap. 5:5-11); of the four chariots coming out from between two mountains of brass with horses of different colors (chap. 6:1-9); of the two staves, Beauty and Bands, with which the prophet in vision is commanded to feed "the flock of the slaughter," and which he is afterwards to break (chap. 11:4-14). For the details in the interpretation of these and other difficult symbols the reader must be referred to the commentaries. Our limits will only allow us to indicate the general principles upon which the expositor must proceed.
9. There is a class of scriptural symbols which may be called numerical. Thus seven is the well-known symbol of completeness, four of universality, twelve of God's people. See Chap. 32, No. 5. Under this head fall also those passages in which a day is put for a year, or for an indefinitely long period of time. One of the most certain examples is Daniel's prophecy of the seventy weeks that were to precede the death of the Messiah (chap. 9:24-27), for the details of which the reader is referred to the commentators. Upon the same principle we must, in all probability, interpret the "time and times and dividing of time," that is, three and a half years (Dan. 7:25); the "forty and two months" (Rev. 11:2; 13:5); and the "thousand two hundred and threescore days" (Rev. 11:3; 12:6). Compare Ezekiel 4:4-8, in which symbolical transaction a day is expressly put as the symbol of a year. On the symbolical interpretation of the six days of creation, see in Chap. 19, No. 6.
