Ezekiel 42:11-20

11 The way before them was like the appearance of [the way of] the chambers which were toward the north; according to their length so was their breadth: and all their exits were both according to their fashions, and according to their doors.
12 According to the doors of the chambers that were toward the south was a door at the head of the way, even the way directly before the wall toward the east, as one enters into them.
13 Then said he to me, The north chambers and the south chambers, which are before the separate place, they are the holy chambers, where the Kohanim who are near to the LORD shall eat the most holy things: there shall they lay the most holy things, and the meal-offering, and the sin-offering, and the trespass-offering; for the place is holy.
14 When the Kohanim enter in, then shall they not go out of the holy place into the outer court, but there they shall lay their garments in which they minister; for they are holy: and they shall put on other garments, and shall approach to that which pertains to the people.
15 Now when he had made an end of measuring the inner house, he brought me forth by the way of the gate whose prospect is toward the east, and measured it round about.
16 He measured on the east side with the measuring reed five hundred reeds, with the measuring reed round about.
17 He measured on the north side five hundred reeds with the measuring reed round about.
18 He measured on the south side five hundred reeds with the measuring reed.
19 He turned about to the west side, and measured five hundred reeds with the measuring reed.
20 He measured it on the four sides: it had a wall round about, the length five hundred, and the breadth five hundred, to make a separation between that which was holy and that which was common.
