Deuteronomy 32:42-46

‘I will make My arrows drunk with blood, And My sword will devour flesh, With the blood of the slain and the captives, From the long-haired leaders of the enemy.’

“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.
