Easton's 1897 Bible Dictionary:

Chamberlain
   a confidential servant of the king (Gen. 37:36; 39:1). In Rom.
   16:23 mention is made of "Erastus the chamberlain." Here the
   word denotes the treasurer of the city, or the quaestor, as the
   Romans styled him. He is almost the only convert from the higher
   ranks of whom mention is made (comp. Acts 17:34). Blastus,
   Herod's "chamberlain" (Acts 12:20), was his personal attendant
   or valet-de-chambre. The Hebrew word _saris_, thus translated in
   Esther 1:10, 15; 2:3, 14, 21, etc., properly means an eunuch (as
   in the marg.), as it is rendered in Isa. 39:7; 56:3.
