“These are the sons of Ehud. They were the heads of the ancestral houses of the inhabitants of Geba. They were carried into exile to Manahath. They were Naaman, Ahijah, and Gera, that is, Heglam, who was the father of Uzza and Ahihud.”
This Ehud, son of Gera, may be the judge in Judges, chapter 3. Apparently, this family or clan settled in Geba, which was a Levite city in Benjamin, about 6 miles north of Jerusalem. They were taken into exile in the 6th century BCE to Manahath, which actually seems like a place in Judah. One of the leaders of this clan was (1) Naaman, mentioned in Numbers, chapter 26, or maybe a brother of Gera. There were 7 different biblical people with the name of (2) Ahijah. The most famous Ahijah was a prophet of Shiloh in the days of King Rehoboam in 1 Kings, chapters 11 and 14. (3) Gera is somehow Heglam, but this is the only mention of Heglam. There are 3 other people with the name of Uzza, but there is also one other Ahihud.
