Verses 8-12 ” 8Then came Amalek, and fought with Israel in Rephidim.
9And Moses said unto Joshua, Choose us out men, and go out, fight with Amalek: to morrow I will stand on the top of the hill with the rod of God in mine hand.
10So Joshua did as Moses had said to him, and fought with Amalek: and Moses, Aaron, and Hur went up to the top of the hill.
11And it came to pass, when Moses held up his hand, that Israel prevailed: and when he let down his hand, Amalek prevailed.
12But Moses hands were heavy; and they took a stone, and put it under him, and he sat thereon; and Aaron and Hur stayed up his hands, the one on the one side, and the other on the other side; and his hands were steady until the going down of the sun.”

Some of the Amalekites were descendants of Esau, mortal enemies of Israel. Israel won the battle, not because of their military greatness, but because of God’s blessing. Moses held up his hands as an act of faith to honor the LORD. Aaron and Hur helped hold up Moses hands. The man of God doing the work of God needs the help of the people of God. It will often seem mundane and unexciting, but it is an honor and so necessary to hold up the hands of the man of God when he is weary.
