44 And Moses came and spoke all the words of this song in the ears of the people, he and Hoshea the son of Nun. 45 And when Moses had ended speaking all these words to all Israel, 46 he said unto them, Set your hearts unto all the words that I testify among you this day, which ye shall command your children to take heed to do, all the words of this law. 47 For it is no vain word for you, but it is your life, and through this word ye shall prolong your days on the land whereunto ye pass over the Jordan to possess it.

Matthew Henry's Commentary on Deuteronomy 32:44-47

Commentary on Deuteronomy 32:44-47

(Read Deuteronomy 32:44-47)

Here is the solemn delivery of this song to Israel, with a charge to mind all the good words Moses had said unto them. It is not a trifle, but a matter of life and death: mind it, and you are made for ever; neglect it, and you are for ever undone. Oh that men were fully persuaded that religion is their life, even the life of their souls!
