One reason seems to have determined the selection of each of these three injunctions, namely, that Israel would be more liable to fail in obedience to these than perhaps any other duties of the law. As for the sabbath, this, like the law of the peace-offering, was a positive, not a moral law; that is, it depended for its authority primarily on the explicit ordinance of God, instead of the intuition of the natural conscience. Hence it was certain that it would only be kept in so far as man retained a vivid consciousness of the Divine personality and moral authority. Moreover, as all history has shown, the law of the sabbath rest from labour constantly comes into conflict with man's love of gain and eager haste to make money. It is a life-picture, true for men of every generation, when Amos (viii. 5) brings before us the Israelites of his day as saying, in their insatiate worldly greed, "When will the sabbath be gone, that we may set forth wheat?" As regards the selection of the second commandment, one can easily see that Israel's loyalty, surrounded as they were on every side with idolaters, was to be tested with peculiar severity on this point, whether they would indeed worship the living God alone and without the intervention of idols.

The circumstances, as regards the peace-offering, were different; but the same principle of choice can be discovered in this also. For among all the various ordinances of sacrificial worship there was none in which the requisitions of the law were more likely to be neglected; partly because these were the most frequent of all offerings, and also because the Israelite would often be tempted, through a short-sighted economy and worldly thriftiness, to use the meat of the peace-offering for food, if any remained until the third day, instead of burning it, in such case, as the Lord commanded. Hence the reminder of the law on this subject, teaching that he who will be holy must not seek to save at the expense of obedience to the holy God.

The second section of this chapter (vv. 9-18) consists of five groups, each of five precepts, all relating to duties which the law of holiness requires from man to man, and each of them closing with the characteristic and impressive refrain, "I am the Lord."

The first of these pentads (vv. 9, 10) requires habitual care for the poor: we read, "Thou shalt not wholly reap the corners of thy field, neither shalt thou gather the gleaning of thy harvest. And thou shalt not glean thy vineyard, neither shalt thou gather the fallen fruit of thy vineyard; thou shalt leave them for the poor and for the stranger."

The law covers the three chief products of their agriculture: the grain, the product of the vine, and the fruit of the trees,—largely olive-trees, which were often planted in the vineyard. So often as God blessed them with the harvest, they were to remember the poor, and also "the stranger," who according to the law could have a legal claim to no land in Israel. Apart from the benefit to the poor, one can readily see what an admirable discipline against man's natural selfishness, and in loyalty to God, this regulation, faithfully observed, must have been. Behind these commands lies the principle, elsewhere explicitly expressed (xxv. 23), that the land which the Israelite tilled was not his own, but the Lord's; and it is as the Owner of the land that He thus charges them that as His tenants they shall not regard themselves as entitled to everything that the land produces, but bear in mind that He intends a portion of every acre of each Israelite to be reserved for the poor. And so the labourer in the harvest-field was continually reminded that in his husbandry he was merely God's steward, bound to apply the product of the land, the use of which was given him, in such a way as should please the Lord.

If the law is not in force as to the letter, let us not forget that it is of full validity as to its spirit. God is still the God of the poor and needy; and we are still every one, as truly as the Hebrew in those days, the stewards of God. And the poor we have with us always; perhaps never more than in these days, in which so great masses of helpless humanity are crowded together in our immense cities, did the cry of the poor and needy so ascend to heaven. And that the Apostles, acting under Divine direction, and abolishing the letter of the theocratic law, yet steadily maintained the spirit and intention of that law in care for the poor, is testified with abundant fulness in the New Testament. One of the firstfruits of Pentecost in the lives of believers was just this, that "all that believed ... had all things common" (Acts ii. 44, 45), so that, going even beyond the letter of the old law, "they sold their possessions and goods, and parted them to all, according as any man had need." And the one only charge which the Apostles at Jerusalem gave unto Paul is reported by him in these words (Gal. ii. 10): "Only they would that we should remember the poor; which very thing I was also zealous to do." Let the believer then remember this who has plenty: the corners of his fields are to be kept for the poor, and the gleanings of his vineyards; and let the believer also take the peculiar comfort from this law, if he is poor, that God, his heavenly Father, has a kindly care, not merely for his spiritual wants, but also for his temporal necessities.

The second pentad (vv. 11, 12) in the letter refers to three of the ten commandments, but is really concerned, primarily, with stealing and defrauding; for the lying and false swearing is here regarded only as commonly connected with theft and fraud, because often necessary to secure the result of a man's plunder. The pentad is in this form: "Ye shall not steal; neither shall ye deal falsely, nor lie one to another. And ye shall not swear by My name falsely, so that thou profane the name of thy God: I am the Lord!"

Close upon stinginess and the careless greed which neglects the poor, with eager grasping after the last grape on the vine, follows the active effort to get, not only the uttermost that might by any stretch of charity be regarded as our own, but also to get something more that belongs to our neighbour. There is thus a very close connection in thought, as well as in position, in these two groups of precepts. And the sequence of thought in this group suggests what is, indeed, markedly true of stealing, but also of other sins. Sin rarely goes alone; one sin, by almost a necessity, leads straight on to another sin. He who steals, or deals falsely in regard to anything committed to his trust, will most naturally be led on at once to lie about it; and when his lie is challenged, as it is likely to be, he is impelled by a fatal pressure to go yet further, and fortify his lie, and consummate his sin, by appealing by an oath to the Holy God, as witness to the truth of his lie. Thus, the sin which in the beginning is directed only toward a fellow-man, too often causes one to sin immediately against God, in profanation of the name of the God of truth, by calling on Him as witness to a lie! Of this tendency of sin, stealing is a single illustration; but let us ever remember that it is a law of all sin that sin ever begets more sin.
