When ye be come into the land - Some learned men are of opinion that several offerings prescribed by the law were not intended to be made in the wilderness, but in the promised land; the former not affording those conveniences which were necessary to the complete observance of the Divine worship in this and several other respects.
To the Israelites of the younger generation is conveyed the hope that the nation should yet enter into the land of promise. The ordinances that follow are more likely to have been addressed to adults than to children; and we may therefore assume that at the date of their delivery the new generation was growing up, and the period of wandering drawing toward its close. During that period the meat-offerings and drink-offerings prescribed by the Law had been probably intermitted by reason of the scanty supply of grain and wine in the wilderness. The command therefore to provide such offerings was a pledge to Israel that it should possess the land which was to furnish the wherewithal for them.
