Ezekiel 42:4-13

MLV(i) 4 And before the chambers was a walk of ten cubits' breadth inward, a way of one cubit and their doors were toward the north. 5 Now the upper chambers were shorter, for the galleries took away from these, more than from the lower and the middlemost, in the building. 6 For they were in three stories and they did not have pillars as the pillars of the courts. Therefore the uppermost was narrowed more than the lowest and the middlemost from the ground. 7 And the wall that was outside by the side of the chambers, toward the outer court before the chambers, the length of it was fifty cubits. 8 For the length of the chambers that were in the outer court was fifty cubits. And behold, of those on the front of the temple were a hundred cubits. 9 And from under these chambers was the entry on the east side, as going into them from the outer court. 10 In the thickness of the wall of the court toward the east, before the separate place and before the building, there were chambers. 11 And 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 And 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 entering into them.
13 Then he said to me, The north chambers and the south chambers, which are before the separate place, they are the holy chambers, where the priests that are near to Jehovah will eat the most holy things. There they will lay the most holy things and the meal offering and the sin offering and the trespass offering, for the place is holy.
