Deuteronomy 32:41-47

41when I sharpen My lightning sword and My hand seizes it in judgment, I will return vengeance on My foes, and those who hate Me I will pay back.

42I will make My arrows drunk from blood, and My sword will devour flesh— the blood of the slain and the captive, the head of the leaders of the enemy.’

43Make His people rejoice, O nations, for He will avenge the blood of His servants. He will return vengeance on His foes, and atone for the land of His people.”

44Then Moses came and spoke all the words of this song in the ears of the people—he and Joshua son of Nun.

45When Moses finished speaking all these words to all Israel,

46he said to them, “Put in your hearts all the words that I call as witness against you today—that you may command your children to keep and do all the words of this Torah.

47For it is not an empty thing for you, because it is your life! By this word you will prolong your days on the land, which you are crossing over the Jordan to possess.”
