Exodus 17:8-16 - Battle With The Amalekites
8 And Amalek will come and will wage war with Israel, in Rephidim. 9 And Moses will say to Joshua, Choose to us men, and go forth, wage war with Amalek: to-morrow I stand upon the head of the hill and the rod of God in my band.
10 And Joshua will do as Moses said to him to wage war with Amalek: and Moses, Aaron and Hur, went up to the head of the hill. 11 And it was as Moses will lift up his hand, Israel prevailed: and as he will put down his hand and Amalek prevailed. 12 And the hands of Moses were heavy; and they will take a stone and put under him, and he will sit upon it: and Aaron and Hur took hold upon his hands, one from here, and one from there; and his hands will be in firmness till the sun went forth. 13 And Joshua will overthrow Amalek and his people with the mouth of the sword.
14 And Jehovah will say to Moses, Write this a remembrance in the book, and set in the ears of Joshua: for wiping off I will wipe off the remembrance of Amalek from under the heavens.
15 And Moses will build an altar, and he will call its name, Jehovah my Standard. 16 For he will say, Because the hand upon the throne of Jehovah, war to Jehovah with Amalek from generation to generation.
