The Greek proper noun Abia (Ἀβιά) is the Greek transliteration of the Hebrew Abiyah — meaning "My Father is Yahweh." It appears in the New Testament in Matthew 1:7 as an ancestor of Jesus in the royal lineage from David to the exile, and in Luke 1:5 as the name of the priestly division to which Zechariah (father of John the Baptist) belonged.
The dual appearances of Abia in the Gospels are deeply significant. In Matthew 1:7, Abijah is part of the royal Davidic lineage leading to the Messiah. In Luke 1:5, the division of Abia connects Zechariah and John the Baptist to the priestly tradition. Thus the name Abia bridges both royal and priestly streams — pointing toward Jesus, who is both King and High Priest (Hebrews 4:14-16; 7:1-3). The historical King Abijah of Judah (1 Kings 15) was mixed in his faithfulness, yet his name — "My Father is Yahweh" — was carried forward in the genealogy of grace, reminding us that God's covenant purposes transcend individual failures.
