Victory over Amalek

⁸Then the Amalekites came and attacked Israel at Rephidim. ⁹Moses told Joshua, "Pick out some men and go fight the Amalekites. Tomorrow I'll stand on top of the hill with the rod of God in my hand." ¹⁰Joshua did what Moses told him and went out to fight the Amalekites. Meanwhile, Moses, Aaron, and Hur climbed to the top of the hill. ¹¹Whenever Moses raised his hand, Israel prevailed. But whenever he lowered his hand, Amalek prevailed. ¹²Moses' hands grew heavy, so they brought a stone and set it under him to sit on. Aaron stood on one side and Hur on the other, each holding up one of his hands. His hands stayed steady until sunset. ¹³Joshua defeated Amalek and his people with the sword. ¹⁴Then the LORD told Moses, "Write this down in a book as a memorial, and make sure Joshua hears it: I will completely erase the remembrance of Amalek from under heaven." ¹⁵Moses built an altar and named it Jehovahnissi — "The LORD Is My Banner." ¹⁶He said, "Because the LORD has sworn that the LORD will be at war with Amalek from generation to generation."
