Deuteronomy 32:42-44 New Revised Standard Version (NRSV)
42 I will make my arrows drunk with blood,
and my sword shall devour flesh—
with the blood of the slain and the captives,
from the long-haired enemy.
43 Praise, O heavens, his people,
worship him, all you gods!
For he will avenge the blood of his children,
and take vengeance on his adversaries;
he will repay those who hate him,
and cleanse the land for his people.
44 Moses came and recited all the words of this song in the hearing of the people, he and Joshua son of Nun.
