What does chamberlain mean in the Bible?

In the Bible, chamberlain means a high-ranking official who managed royal chambers, household, or treasury, similar to steward, treasurer, or chief of staff, and is translation of Hebrew and Greek terms for eunuch or officer in charge of bedchamber. Chamberlain appears in Old and New Testaments. In Old Testament, Hebrew word saris is translated as chamberlain or eunuch, referring to official in charge of king's harem and private chambers, like in Esther, where chamberlains guarded king's concubines. In 2 Kings, chamberlains served kings. In New Testament, Greek word oikonomos or eunouchos is translated as chamberlain. For example, in Acts 12:20, Blastus was Herod's chamberlain, meaning personal servant managing household. In Romans 16:23, Erastus is called chamberlain of city of Corinth, meaning city treasurer or manager of city finances, Greek oikonomos. So biblical chamberlain was trusted official managing private quarters, finances, or city treasury, often eunuch in ancient Near Eastern courts to protect harem. Chamberlains had great power and access to king. So in Bible, chamberlain means high official, steward, treasurer, or keeper of bedchamber, not just servant but influential manager of royal household or city finances, often translated as officer or eunuch.
