Ezekiel 42:16 KJV

15Now 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.

16He measured the east side with the measuring reed, five hundred reeds, with the measuring reed round about.

17He measured the north side, five hundred reeds, with the measuring reed round about.

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