Ezekiel 40:17

A chamber with its doorway was by the side pillars at the gates; there they rinse the burnt offering.

From the outside to the inner gate were chambers for the singers in the inner court, one of which was at the side of the north gate, with its front toward the south, and one at the side of the south gate facing toward the north.

Then he said to me, “This is the chamber which faces toward the south, intended for the priests who keep the responsibility of the house;

but the chamber which faces toward the north is for the priests who keep the responsibility of the altar. These are the sons of Zadok, who from the sons of Levi come near to Yahweh to minister to Him.”

Then he brought me to the nave and measured the side pillars; six cubits wide on each side was the width of the side pillar.

and the outer chambers was twenty cubits in width all around the house on every side.

Then he brought me out into the outer court, the way toward the north; and he brought me to the chamber which was opposite the separate area and opposite the building toward the north.

Opposite the twenty cubits which belonged to the inner court, and opposite the pavement which belonged to the outer court, was gallery corresponding to gallery in three stories.

In the thickness of the wall of the court toward the east, facing the separate area and facing the building, there were chambers.

Then He brought me back by the way of the outer gate of the sanctuary, which faces the east; and it was shut.

Then a measuring rod like a staff was given to me, saying, “Get up and measure the sanctuary of God and the altar, and those who worship in it.

“And leave out the court which is outside the sanctuary and do not measure it, for it has been given to the Gentiles, and they will trample the holy city under foot for forty-two months.
