28, 29. At the end of three years . . . the Levite . . . shall come, &c.—The Levites having no inheritance like the other tribes, the Israelites were not to forget them, but honestly to tithe their increase [Nu 18:24]. Besides the tenth of all the land produce, they had forty-eight cities, with the surrounding grounds [Nu 35:7], "the best of the land," and a certain proportion of the sacrifices as their allotted perquisites. They had, therefore, if not an affluent, yet a comfortable and independent, fund for their support.

     9-12. Seven weeks shalt thou number—The feast of weeks, or a WEEK OF WEEKS: the feast of pentecost (see on Le 23:10; also see Ex 34:22; Ac 2:1). As on the second day of the passover a sheaf of new barley, reaped on purpose, was offered, so on the second day of pentecost a sheaf of new wheat was presented as first-fruits (Ex 23:16; Nu 28:26), a freewill, spontaneous tribute of gratitude to God for His temporal bounties. This feast was instituted in memory of the giving of the law, that spiritual food by which man's soul is nourished (De 8:3).

     16-18. The fathers shall not be put to death for the children—The rule was addressed for the guidance of magistrates, and it established the equitable principle that none should be responsible for the crimes of others.

     19-22. When thou cuttest down thine harvest in thy field—The grain, pulled up by the roots or cut down with a sickle, was laid in loose sheaves; the fruit of the olive was obtained by striking the branches with long poles; and the grape clusters, severed by a hook, were gathered in the hands of the vintager. Here is a beneficent provision for the poor. Every forgotten sheaf in the harvest-field was to lie; the olive tree was not to be beaten a second time; nor were grapes to be gathered, in order that, in collecting what remained, the hearts of the stranger, the fatherless, and the widow might be gladdened by the bounty of Providence.
