“Keeping the rod in the UP position”

A sermon on Exodus 17:11-13

And it came to pass, when Moses held up his hand, that Israel prevailed; and when he let down his hand, Amalek prevailed. 12 But 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. 13 And Joshua discomfited Amalek and his people with the edge of the sword.
