Deuteronomy 32:43

Verse 43. People. Though God afflicted the Israelites for a time, he was always disposed to receive them to his favour again upon their repentance; and he will even receive them into his Church before the day of judgment. Romans 11:25. Calmet.—This decided predilection for them, would naturally induce other nations to praise them. Grabe’s Septuagint reads, “Rejoice ye heavens with him, and let all the sons of God adore him, and let all the angels of God strengthen them, because He revengeth the blood of his sons; and he will continue to do so, and he will punish his enemies, and will render to those who hate him; and the Lord will purify the land of his people.” Bible.—In some editions, after Let all the angels of God adore him, (cited Hebrews 1:6. Cappel.) they read, Rejoice, ye Gentiles, with his people, which Saint Paul quotes, Romans 15:10; and then they add, “And Moses wrote this canticle on that day, and he taught it to the children of Israel; ( Calmet.) 44 and Moses came forth to the people, and spoke all the words of this law, in the ears of the people, he and Jesus, the son of Nave,” by which name they designate Josue, the son of Nun. Bible.—He assisted Moses in singing the canticle, as his colleague in office, to whom the obligation of withdrawing the people from idolatry would henceforth devolve. Menochius.—God always preserved some of the Jews from the general corruption, till the time of the Messias. Worthington.

For this verse, LXX reads: Rejoice, you heavens, with him, and let all the angels of God worship him; rejoice you Gentiles, with his people, and let all the sons of God strengthen themselves in him; for he will avenge the blood of his sons, and he will give vengeance, and recompense justice to his enemies, and will reward them that hate him; and the Lord shall purge the land of his people.
