1. Son of Phinehas, fourth high priest (1 Chronicles 6:50). The Chronicon of Alexandria shows that his pontificate included the period of Ehud's judgeship, and probably of Eglon's oppression. Father of Bukki (1 Chronicles 6:4-5; 1 Chronicles 6:50-51; Ezra 7:4-5). Josephus (Ant. 8:1, 3) says he was succeeded in the priesthood by Eli; his descendants, until Zadok, falling to the rank of private persons.
2. Son of Bela of Benjamin: 1 Chronicles 8:4.
