The Hebrew proper noun Abi (אֲבִי) is a personal name meaning "My Father" or possibly "(The LORD is) my Father." The name appears in 2 Kings 18:2 as the name of Hezekiah's mother, daughter of Zechariah. She is also called Abijah (H29) in 2 Chronicles 29:1, the longer form of the same name. The name reflects the ancient Hebrew practice of embedding theological confession in personal names.
The name Abi — "My Father" — speaks to the deeply personal nature of Israel's relationship with God. In an era when the nations named their children after Baal, Molech, or Asherah, Israelite names like Abi, Abijah, and Abraham declared allegiance to the covenant God. Hezekiah's mother bore a name that proclaimed God as Father — and Hezekiah himself became one of Judah's most faithful kings (2 Kings 18:5). The name anticipates the fullness revealed in the New Testament, where Jesus teaches His disciples to address God as Abba, Father (Romans 8:15). The family relationship with God that Israel glimpsed is made fully accessible in Christ.
