Ezekiel 42:16

Then he said to me, “The north rooms and the south rooms, which are opposite the separate place, are the holy rooms, where the priests who are near to the LORD shall eat the most holy things. There they shall lay the most holy things, with the meal offering, the sin offering, and the trespass offering; for the place is holy.

When the priests enter in, then they shall not go out of the holy place into the outer court until they lay their garments in which they minister there; for they are holy. Then they shall put on other garments, and shall approach that which is for the people.”

Now when he had finished measuring the inner house, he brought me out by the way of the gate which faces toward the east, and measured it all around.

He measured on the north side five hundred reeds with the measuring reed all around.

He measured on the south side five hundred reeds with the measuring reed.

He turned about to the west side, and measured five hundred reeds with the measuring reed.
