8 Then the Amalek army came and attacked Israel at Refidim, 9 and Mosheh instructed Yehoshua (Joshua), “Choose men for us and go out and fight with Amalek. Tomorrow I’ll be stationed on top of the hill with the staff of God in my hand.” 10 So Yehoshua prepared to fight Amalek as Mosheh had told him, and Mosheh, Aharon, and Hur climbed up to the top of the hill. 11 And so it happened that when Mosheh raised his arm, then Israel would be winning, but when he lowered his arm, then Amalek would start winning. 12 However, Mosheh’s arms got tired, so they got a large stone and sat him on it, and Aharon and Hur stood on each side of him holding up his arms, and holding him steady in that position until the sun went down. 13 So this was how Yehoshua defeated Amalek and his army with their swords. 14 Then Yahweh told Mosheh, “Write this event in the book and read it aloud to Yehoshua, because I will certainly blot out the memory of Amalek from off the earth.”[ref]
