The Greek word Amminadab (G301) is a transliteration of the Hebrew name Amminadav (H5992), meaning "my people are willing" or "my kinsman is noble." It appears in Matthew 1:4 and Luke 3:33 in the genealogies of Jesus Christ.
Amminadab was the father of Nahshon, who was the father of Salmon, who was the father of Boaz in the line from Judah to David to Christ.
Amminadab sits at a crucial juncture in the genealogies of Jesus — the Davidic line runs directly through him. His son Nahshon was the tribal leader of Judah during the wilderness period (Numbers 1:7) and led his tribe in the processional order before the ark.
The inclusion of Amminadab in both Matthew's and Luke's genealogies affirms that Jesus' Messianic credentials are grounded in real history — specific people, specific lineages, specific fulfillments of covenant promise. "The book of the genealogy of Jesus Christ, the son of David, the son of Abraham" (Matthew 1:1) is a declaration that redemption happens in time, through families, in the stuff of ordinary human generations.
