Exodus 17:10 - Clarke's commentary and critical notes on the Bible

So 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. Moses, Aaron, and Hur went up - It is likely that the Hur mentioned here is the same with that Hur mentioned 1 Chronicles 2:19, who appears from the chronology in that chapter to have been the son of Caleb, the son of Ezron, the son of Pharez, the son of Judah. The rabbins and Josephus say he was the brother-in-law of Moses, having married his sister Miriam. He was a person in whom Moses put much confidence; for he left him conjoint governor of the people with Aaron, when he went to confer with God on the mount, Exodus 24:14. His grandson Bezaleel was the chief director in the work of the tabernacle; see Exodus 31:2-5.
