Amalek Fought

9 So Moses said to 3Joshua, "Choose men for us and go out, fight against Amalek. Tomorrow I will station myself on the top of the hill with 4the staff of God in my hand."
10 Joshua did as Moses told him, and fought against Amalek; and Moses, Aaron, and 5Hur went up to the top of the hill.
11 So it came about when Moses held his hand up, that Israel prevailed, and when he let his hand down, Amalek prevailed.
12 But Moses' hands were heavy. Then they took a stone and put it under him, and he sat on it; and Aaron and Hur 6supported his hands, one on one side and one on the other. Thus his hands were steady until the sun set.
13 So Joshua overwhelmed Amalek and his people with the edge of the sword.
14 Then the LORD said to Moses, "7Write this in a book as a memorial and recite * it to Joshua, that 8I will utterly blot out the memory of Amalek from under heaven."
15 Moses built an 9altar and named * it 10The LORD is My Banner;
16 and he said, "11The LORD has sworn * *; the LORD will have war against Amalek from generation to generation."
