Armies: March in Ranks: when Aaron and Hur Held up Moses' Hands
Source: Nav
Exodus 17:11, 12
As long as Moses held up his hands, Israel prevailed; but when he lowered them, Amalek prevailed. / When Moses’ hands grew heavy, they took a stone and put it under him, and he sat on it. Then Aaron and Hur held his hands up, one on each side, so that his hands remained steady until the sun went down.
