The Importance of Uri in Exodus

Uri is the son of Huar, who I don't know if there's anything that you got here on Huar L. But he is kind of one of the more major minor characters in the Exodus story. He and Aaron were the ones who held up Moshe's arms so that they could defeat on the left. So he's a pretty important person apparently. What I do know about that is in the list of people who already live in the land of Kanaan, there's like the Thivi and there's also the Hurim.
