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 4:19,20 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; 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; 2:3; 7:12; 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 15:10,11 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).
