Exodus 17:12-14

Amplified Bible

¹² But Moses’ hands were heavy and he grew tired. So they took a stone and put it under him, and he sat on it. Then Aaron and Hur held up his hands, one on one side and one on the other side; so it was that his hands were steady until the sun set. ¹³ So Joshua overwhelmed and defeated ^[a]Amalek and his people with the edge of the sword.

¹⁴ Then the Lord said to Moses, “Write this in the book as a memorial and ^[b]recite it to Joshua, that I will utterly wipe out the memory of Amalek [and his people] from under heaven.”^(A)
