Benjamin comes from Hebrew and is traditionally rendered "son of the right hand," an idiom historically tied to favor, strength, or a place of honor within a family. The biblical Benjamin was the youngest and most cherished of his brothers, and the name has kept that undertone of being treasured rather than merely counted among many.
