Ezekiel 42:15

12 And under the rooms on the south was a door at the head of the outer wall in the direction of the east as one goes in.

13 And he said to me, The north rooms and the south rooms in front of the separate place are the holy rooms, where the priests who come near the Lord take the most holy things for their food: there the most holy things are placed, with the meal offering and the sin-offering and the offering for error; for the place is holy.

14 When the priests go in, they may not go out of the holy place into the outer square, and there they are to put the robes in which they do the work of the Lord's house, for they are holy: and they have to put on other clothing before they come near that which has to do with the people.

15 And when he had come to the end of measuring the inner house, he took me out to the doorway looking to the east, and took its measure all round.

16 He went round and took the measure of it on the east side with the measuring rod, five hundred, measured with the rod all round.

17 And he went round and took the measure of it on the north side with the measuring rod, five hundred, measured with the rod all round.

18 And he went round and took the measure of it on the south side with the measuring rod, five hundred, measured with the rod all round.
