Verse 28. - Call heaven and earth to record against them (cf. Deuteronomy 32:1). These words; the words of his charge, and especially the song he had composed, and which it would be the business of these officers to teach to the congregation.

31:23-30 The solemn delivery of the book of the law to the Levites, to be deposited in, or rather by the side, of the ark, is again related. The song which follows in the next chapter is delivered to Moses, and by him to the people. He wrote it first, as the Holy Spirit taught him; and then spake it in the hearing of all the people. Moses tells them plainly, I know that after my death ye will utterly corrupt yourselves. Many a sad thought, no doubt, it occasioned to this good man; but his comfort was, that he had done his duty, and that God would be glorified in their dispersion, if not in their settlement, for the foundation of God stands sure.Gather unto me all the elders of your tribes, and your officers,.... The heads of the tribes, the princes, and all other inferior magistrates:

that I may speak these words in their ears; not the words of the law, but of the song which he was ordered to write, and is recorded in the following chapter:

and call heaven and earth to record against them; to bear witness of what he delivered to them, and to bear witness against them should they transgress the laws he gave them; and to bear witness that they had been faithfully cautioned against transgressing, and had been severely threatened, and the punishment plainly pointed out that should be inflicted on them in case of disobedience, so that they were left entirely without excuse.
