The rooms for the singers and priests 40:44-46

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.⁵²³It was for the use of singers and the priests in charge of the altar (cf. 43:13-17). These priests were descendants of Zadok, the faithful high priest who served during David and Solomon's reigns (cf. 44:15; 1 Sam. 2:31-33; 2 Sam. 15:24-29; 1 Kings 1:5-26, 32-35; 2:26-27, 35; 1 Chron. 6:3-8; 24:3).
