Deuteronomy 32:40-42

MSTC(i) 40 For I will lift up my hand to heaven, and will say: I live ever. 41 If I whet the lightning of my sword, and mine hand take in hand to do justice, I will show vengeance on mine enemies and will reward them that hate me. 42 I will make mine arrows drunken with blood, and my sword shall eat flesh of the blood of the slain and of the captive and of the bare head of the enemy.'
