Ezekiel 42:13-17

Then he said to me, “The north chambers and the south chambers, which are opposite the separate area, they are the holy chambers where the priests who are near to the Lord shall eat the most holy things. There they shall set the most holy things, the grain offering, the sin offering, and the guilt offering; for the place is holy.

When the priests enter, they shall not go out into the outer courtyard from the sanctuary without laying their garments there in which they minister, for they are holy. They shall put on other garments; then they shall approach that which is for the people.”

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

He measured on the east side with the measuring rod: five hundred rods by the measuring rod.

He measured on the north side: five hundred rods by the measuring rod.
