Deuteronomy 32:43-47

“Rejoice, you nations, with His people; For He will avenge the blood of His servants, And will return vengeance on His adversaries, And will atone for His land and His people.”

Then Moses came and spoke all the words of this song in the hearing of the people, he, with Joshua the son of Nun.

When Moses had finished speaking all these words to all Israel,

he said to them, “Take to your heart all the words with which I am warning you today, which you will command your sons to follow carefully, all the words of this Law.

For it is not a trivial matter for you; indeed it is your life. And by this word you will prolong your days in the land, which you are about to cross the Jordan to possess.”
