This name appears in Ezra's list of returning exiles, meaning 'hero' or 'mighty one' in Aramaic. The parallel list in Nehemiah has 'Gibeon' instead, suggesting Gibbar may represent the people of Gibeon or a textual variant. Such variations between Ezra and Nehemiah's parallel lists are common, reflecting different manuscript traditions or actual name variations. The name's meaning ('hero') makes it suitable as either a personal name or a gentilicial derived from a place name.
