Holman Bible Dictionary
(gab' bay i) Personal name traditionally interpreted as meaning, “tax collector.” Member of tribe of Benjamin who settled in Jerusalem in time of Nehemiah (Nehemiah 11:8 ). Many modern commentators think copying errors have introduced the name into the text from an original Hebrew text meaning, “heroic men,” though no existing Hebrew text has this reading.
