Other individuals named Hur are also mentioned in the Bible.
Hur, companion of Moses
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". 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." However, only Aaron is mentioned in the later account of events during Moses' absence and the creation of the Golden Calf.
In the Books of Chronicles Hur is either the son or the father of Caleb. The language is sufficiently ambiguous that different interpretations are possible. The King James Version of the Bible states "These were the sons of Caleb the son of Hur, the firstborn of Ephratah; Shobal the father of Kirjathjearim...." The New International Version has "These were the sons of Caleb. The sons of Hur, the firstborn of Ephrathah, were Shobal the father of Kiriath-jearim...." The second version places Hur as the first child of Caleb by his second wife Ephrath.
Hur had four sons, Uri the father of Bezaleel, and three others, Shobal, Salma and Hareph, who are said to have been the founders of the towns of Kirjath-jearim, Bethlehem, and Bethgader respectively. However, I Chronicles calls Hur himself the father of Bethlehem.
To explain the close links between Moses and Hur, Josephus in Antiquities of the Jews states that Hur was the husband of Moses' sister Miriam. However, in the Targum to I Chron. ii. 19, iv. 4, Miriam is said to be Hur's mother, asserting that Ephrath was another name for Miriam.
In Talmudic tradition the sudden disappearance of Hur from the narrative of Exodus is explained by the claim that Hur was killed when he tried to prevent the making of the Golden Calf. The murder of Hur intimidated Aaron into complying with the popular demand to create the idol. Hur's faithfulness was rewarded by God by granting his grandson the role of making the Tabernacle.
It is the traditional view that Hur the companion of Moses is the same as the grandfather of Bezaleel, but this is not certain. Other persons named Hur include:
Hur, a King of the Midianites
He was killed with four other Midianite kings during the time of Moses by an Israelite expedition led by Phinehas, son of Eleazar. Baalam, son of Beor, was also slain by the Israelites in this expedition (Num. 31:8; Joshua 13:21).
Hur, Father of an Officer of Solomon
He is only mentioned in this verse, and the name of his son is not mentioned (1 Kings 4:8); there is no other biographical data regarding him. While it is possible it could refer to one of the other persons by the name of Hur (other than the King of Midian) who was an ancestor of the officer and not a biological father, it is extremely unlikely.
Hur, the Father of Rephaiah
He is only mentioned in his relationship to Rephaiah (Nehemiah 3:9); there is no other biographical data regarding him. While it is possible it could refer to one of the other persons by the name of Hur (other than the King of Midian) if "Rephaiah the son of Hur" means Hur was an ancestor and not a biological father, it is extremely unlikely.
