Ezekiel 42:14-18

When the priests enter therein, then shall they not go out of the holy place into the utter court, but there they shall lay their garments wherein they minister; for they are holy; and shall put on other garments, and shall approach to those things which are for the people.

Now when he had made an end of measuring the inner house, he brought me forth toward the gate whose prospect is toward the east, and measured it round about.

He measured the east side with the measuring reed, five hundred reeds, with the measuring reed round about.

He measured the north side, five hundred reeds, with the measuring reed round about.

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