Deuteronomy 32:43

40 For I lift up my hand to heaven, And say, As I live for ever,

41 If I whet my glittering sword, And my hand take hold on judgment; I will render vengeance to mine adversaries, And will recompense them that hate me.

42 I will make mine arrows drunk with blood, And my sword shall devour flesh; With the blood of the slain and the captives, From the head of the leaders of the enemy.

43 Rejoice, O ye nations, [with] his people: For he will avenge the blood of his servants, And will render vengeance to his adversaries, And will make expiation for his land, for his people.

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.

45 And Moses made an end of speaking all these words to all Israel;

46 And he said unto them, Set your heart unto all the words which I testify unto you this day, which ye shall command your children to observe to do, [even] all the words of this law.
