The name Zadok means 'righteous' or 'justified' in Hebrew. It is derived from the Hebrew word 'צָדוֹק' (Ṣādōq), which conveys the idea of moral integrity and justice. This name is notably associated with several biblical figures, most prominently the High Priest of Israel during the reigns of Kings David and Solomon. Zadok played a crucial role in anointing Solomon as king and served as the first High Priest in Solomon's Temple.
