The Hebrew Iezri (אִיעֶזְרִי) is the gentilic adjective for a member of the clan descended from Iezer (Abiezer) of the tribe of Manasseh. It appears in Numbers in the census of Israel's clans before entering the Promised Land. Gideon the judge was an Iezerite (Abiezrite), making this designation the family identity of one of Israel's most celebrated deliverers.
The gentilic names in Israel's tribal lists — Iezerite, Machirite, Gileadite — are not bureaucratic labels but identity markers connecting individuals to covenant community. To be an Iezerite was to belong to a clan whose very name declared 'my father is help.' In a real sense, one's gentilic identity was a theological statement — your family stood within the covenant God made with Abraham, Isaac, and Jacob. When Gideon said 'My clan is the weakest in Manasseh, and I am the least in my family' (Judg 6:15), his Abiezrite/Iezerite identity made his calling all the more remarkable: the weakest branch of a clan named 'father-is-help' was chosen, because God delights to demonstrate His help through the weak.
