Aaron and Hur holding up the arms of Moses.
In the biblical story of Exodus, Aaron and Hur held up Moses' arms during the battle against the Amalekites because his hands needed to be raised to the heavens while he prayed for the Israelites' victory. When Moses lowered his hands, the Israelites suffered, and when his hands were raised, they prevailed. Aaron and Hur provided support so that Moses could maintain his outstretched posture for the duration of the battle, ensuring the Israelites' victory until sunset.
