There were two rooms for singers in the inner court. One of them stood beside the north inner gate, and its door faced south. It also accommodated the needs of the priests who were responsible for the care of the temple. The other room stood beside the south inner gate, and its door faced north. The Septuagint translators assumed that this room stood beside the south inner gate because this gives a more symmetrical arrangement. This is probably correct even though the Hebrew text locates it beside the east inner gate (cf. Ezekiel 42:10). This room was for the use of singers and the priests in charge of the altar (cf. Ezekiel 43:13-17). These priests were descendants of Zadok, the faithful high priest who served during David and Solomon"s reigns (cf. Ezekiel 44:15; 1 Samuel 2:31-33; 2 Samuel 15:24-29; 1 Kings 1:5-26; 1 Kings 1:32-35; 1 Kings 2:26-27; 1 Kings 2:35; 1 Chronicles 6:3-8; 1 Chronicles 24:3). [source][source][source]
