8 ^fThen Amalek came and fought with Israel at Rephidim. 9 So Moses said to ^gJoshua, “Choose for us men, and go out and fight with Amalek. Tomorrow I will stand on the top of the hill with ^hthe staff of God in my hand.” 10 So ^gJoshua did as Moses told him, and fought with Amalek, while Moses, Aaron, and ⁱHur went up to the top of the hill. 11 Whenever Moses ^jheld up his hand, Israel prevailed, and whenever he lowered his hand, Amalek prevailed. 12 But Moses’ hands grew weary, so they took a stone and put it under him, and he sat on it, while Aaron and ⁱHur held up his hands, one on one side, and the other on the other side. So his hands were steady until the going down of the sun. 13 And ^gJoshua overwhelmed Amalek and his people with the sword.

14 Then the Lord said to Moses, “Write this as a memorial in a book and recite it in the ears of ^gJoshua, that ^kI will utterly blot out the memory of Amalek from under heaven.” 15 And Moses ^lbuilt an altar and called the name of it, The Lord Is My Banner, 16 saying, “A hand upon the throne¹ of the Lord! ^kThe Lord will have war with Amalek from generation to generation.”
