A royal official responsible for the king's private quarters. They sometimes had important tasks and had influence with those in power (Acts 12:20). The chamberlain Erastus was actually the city treasurer (Romans 16:23). Nathan-melech the chamberlain was a court official at the time of Josiah (2 Kings 23:11). The Persian kings used eunuchs (men who were physically unable to have children) as chamberlains (Esther 1:10, 12, 15; 2:3, 14–15; 4:4–5; 6:2, 14; 7:9).
