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.
