Ezekiel 40:44-46

Young's Literal Translation

⁴⁴ And on the outside of the inner gate [are] chambers of the singers, in the inner court, that [are] at the side of the north gate, and their fronts [are] southward, one at the side of the east gate [hath] the front northward.

⁴⁵ And he speaketh unto me: `This chamber, whose front [is] southward, [is] for priests keeping charge of the house;

⁴⁶ and the chamber, whose front [is] northward, [is] for priests keeping charge of the altar: they [are] sons of Zadok, who are drawing near of the sons of Levi unto Jehovah, to serve Him.'
