Ezekiel 40:44-49

⁴⁴And without the inner gate were the chambers of the singers in the inner court, which was at the side of the north gate; and their prospect was toward the south: one at the side of the east gate having the prospect toward the north. ⁴⁵And he said unto me, This chamber, whose prospect is toward the south, is for the priests, the keepers of the charge of the house. ⁴⁶And the chamber whose prospect is toward the north is for the priests, the keepers of the charge of the altar: these are the sons of Zadok among the sons of Levi, which come near to the LORD to minister unto him. ⁴⁷So he measured the court, an hundred cubits long, and an hundred cubits broad, foursquare; and the altar that was before the house.

⁴⁸And he brought me to the porch of the house, and measured each post of the porch, five cubits on this side, and five cubits on that side: and the breadth of the gate was three cubits on this side, and three cubits on that side. ⁴⁹The length of the porch was twenty cubits, and the breadth eleven cubits; and he brought me by the steps whereby they went up to it: and there were pillars by the posts, one on this side, and another on that side.
