Yechezkel 42:14-16

Orthodox Jewish Bible

¹⁴ When the Kohanim enter therein, then shall they not go out of the Kodesh into the khatzer hakhitzonah, but there they shall lay their garments wherein they minister; for they are kodesh; and shall put on begadim acherim (other garments); then shall they approach the precinct of the people.

¹⁵ Now when he [the angelic being] had made an end of measuring the Beis HaPenimi, he brought me forth toward the sha’ar whose view is toward the east, and measured it all around.

¹⁶ He measured the eastern side with the measuring rod, five hundred rods, with the keneh hamiddah (measuring rod) all around.
