Ezekiel 42:16

14When 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.”

15Now 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.

16He measured on the east side with the measuring reed five hundred reeds, with the measuring reed all around.

17He measured on the north side five hundred reeds with the measuring reed all around.

18He measured on the south side five hundred reeds with the measuring reed.
