Matthew Poole and continuators on Deuteronomy 32:44

44 And Moses came, and spake all the words of this song in the ears of the people, he, and Hoshea the son of Nun.

Or Ioshua: who is here joyned with Moses in this action, because though Moses onely spake the words, yet Ioshua consented to them, and, it may be, afterwards repeated them; this being not a song to be sung once for all, but a standing monument which was written and kept for future use, Deut. 31. 22, &c. and to be repeated again and again upon solemn occasions, which Ioshua and other succeeding Magistrates were to take care of.

Marginal references: Or, Ioshua.
