(1) In Rth 4:19, Rth 4:20 and 1 Chronicles 2:10 Amminadab is referred to as one of David's ancestors. He was the great-grandson of Perez, a son of Judah ( Genesis 38:29; Genesis 46:12 ) and the great-grandfather of Boaz, who again was the great-grandfather of David. Aaron's wife, Elisheba, was a daughter of Amminadab (Exodus 6:23 ), while one of the sons, namely, Nahshon, occupied an important position in the Judah-clan (Numbers 1:7; Numbers 2:3; Numbers 7:12; Numbers 10:14 ).
(2) In the first Book of Chronicles (1 Chronicles 6:22 ) Amminadab is mentioned as a son of Kohath (and therefore a grandson of Levi) and the father of Korah. But in other genealogical passages (Exodus 6:18; Numbers 3:19; 1 Chronicles 6:2 ) the sons of Kohath are Amram, Izhar, Hebron and Uzziel, and in two places (Exodus 6:21; 1 Chronicles 6:38 ) Izhar is mentioned as the father of Korah.
(3) According to 1 Ch (1 Chronicles 15:10 , 1 Chronicles 15:11 ) Amminadab was the name of a priest who took part in the removal of the ark to Jerusalem. He was the son of Uzziel, and therefore a nephew of Amminadab, son of Kohath (= Izhar).
