Deuteronomy 32:40
39 “See now that I, indeed I, am he!” says the Lord, “and there is no other god besides me. I kill and give life, I smash and I heal, and none can resist my power. 40 For I raise up my hand to heaven, and say, ‘As surely as I live forever, 41 I will sharpen my lightning-like sword, and my hand will grasp hold of the weapon of judgment; I will execute vengeance on my foes, and repay those who hate me! 42 I will make my arrows drunk with blood, and my sword will devour flesh—the blood of the slaughtered and captured, the chief of the enemy’s leaders.’”
Daniel 12:7
6 One said to the man clothed in linen who was above the waters of the river, “When will the end of these wondrous events occur?” 7 Then I heard the man clothed in linen who was over the waters of the river as he raised both his right and left hands to the sky and made an oath by the one who lives forever: “It is for a time, times, and half a time. Then, when the power of the one who shatters the holy people has been exhausted, all these things will be finished.” 8 I heard, but I did not understand. So I said, “Sir, what will happen after these things?”
Notes and References
"... The oath reported by Daniel has in turn its antecedent in an oath sworn by YHWH himself. Before Moses dies, he teaches the Israelites a song that he has learned from YHWH, a song that will serve as a 'witness' against the Israelites when they enter Canaan and abandon their god (Deuteronomy 31:19). In its present context, the Song of Moses predicts how the Israelites will serve other gods, and how YHWH will punish his people by arranging their military defeat. Then will YHWH taunt his people, advising them to seek the aid of those other gods they had served ..."
