Exodus 17:9-14 And Moses said to Joshua, Choose out for yourself mighty men, and go forth and set the army in array against Amalec to-morrow; and, behold, I shall stand on the top of the hill, and the rod of God will be in my hand.

LXX2012⁽ⁱ⁾ ⁹ And Moses said to Joshua, Choose out for yourself mighty men, and go forth and set the army in array against Amalec to-morrow; and, behold, I [shall] stand on the top of the hill, and the rod of God [will be] in my hand. ¹⁰ And Joshua did as Moses said to him, and he went out and set the army in array against Amalec, and Moses and Aaron and Or went up to the top of the hill. ¹¹ And it came to pass, when Moses lifted up his hands, Israel prevailed; and when he let down his hands, Amalec prevailed. ¹² But the hands of Moses were heavy, and they took a stone and put it under him, and he sat upon it; and Aaron and Or supported his hands one on this side and the other on that, and the hands of Moses were supported till the going down of the sun. ¹³ And Joshua routed Amalec and all his people with the slaughter of the sword. ¹⁴ And the Lord said to Moses, Write this for a memorial in a book, and speak [this] in the ears of Joshua; for I will utterly blot out the memorial of Amalec from under heaven.
