Ezekiel 40:44-46 - Rooms For Priests And Other Worship Leaders
44 And on the outside of the inner gate, [there were] chambers for singers in the inner courtyard, which [was] to the side of the north gate, and their faces {were to the south} [with respect to one], [and] on the side of the east gate [one] facing to the north. 45 And he said to me, "This chamber {with its face toward the south} [is] for the priests [who are] taking care of the responsibility of the temple. 46 And the chamber {with its face to the north} [is] for the priests [who are] taking care of the responsibility of the altar. They [are] the descendants of Zadok, the [ones who] approach [from among] the descendants of Levi to Yahweh to serve him."
