In the Book of Exodus, Hur is first mentioned as a companion of Moses and Aaron watching the Battle of Rephidim against the Amalekites. He aided Aaron to hold up the hands of Moses when Moses realised that the Israelites prevailed in battle while his hands were raised: "Aaron and Hur stayed up his hands, the one on the one side, and the other on the other side".[1] He is mentioned once more as Moses' staunch ally when he is left in co-charge with Aaron of the Israelites when Moses was away on Mount Sinai. Moses told the people "Aaron and Hur are with you; whosoever hath a cause, let him come near unto them."[2] However, only Aaron is mentioned in the later account of events during Moses' absence and the creation of the Golden Calf.
