Ezekiel 42:14-16

Young's Literal Translation

¹⁴ In the priests' going in, they come not out from the sanctuary unto the outer court, and there they place their garments with which they minister, for they [are] holy, and have put on other garments, and have drawn near unto that which [is] for the people.'

¹⁵ And he hath finished the measurements of the inner house, and hath brought me forth the way of the gate whose front [is] eastward, and he hath measured it all round about.

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