During Ahab's reign, Hiel the Bethelite rebuilt Jericho. Abiram, his firstborn son, died when he laid the foundation; Segub, his youngest son, died when he erected its gates, just as the Lord had warned through Joshua son of Nun.

Later Hezron had sexual relations with the daughter of Makir, the father of Gilead. (He had married her when he was sixty years old.) She bore him Segub.

Segub was the father of Jair, who owned twenty-three cities in the land of Gilead.
