Amminadab a-min'-a-dab (`amminadhabh = "my people (or my kinsman) is generous or noble"): Three persons bearing this name are mentioned in the Old Testament.
(1) In Ruth 4:19, Ruth 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 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).
