Ezekiel 40:15-25

15 The total length of the gateway from the outside wall of the gate to the far side of the last room was 84 feet.
16 There were small openings in the outside walls of all the rooms and also in the inner walls between the rooms. There were palm trees carved on the inner walls that faced the passageway.
17 The man took me through the gateway into the courtyard. There were thirty rooms built against the outer wall, and in front of them there was an area paved with stones,
18 which extended around the courtyard. This outer courtyard was at a lower level than the inner courtyard.
19 There was a gateway at a higher level that led to the inner courtyard. The man measured the distance between the two gateways, and it was 168 feet.
20 Then the man measured the gateway on the north side that led into the outer courtyard.
21 The three guardrooms on each side of the passageway, the walls between them, and the entrance room all had the same measurements as those in the east gateway. The total length of the gateway was 84 feet and the width 42 feet.
22 The entrance room, the windows, and the carved palm trees were like those in the east gate. Here seven steps led up to the gate, and the entrance room was at the end facing the courtyard.
23 Across the courtyard from this north gateway was another gateway leading to the inner courtyard, just as there was on the east side. The man measured the distance between these two gateways, and it was 168 feet.
24 Next, the man took me to the south side, and there we saw another gateway. He measured its inner walls and its entrance room, and they were the same as the others.
25 There were windows in the rooms of this gateway just as in the others. The total length of the gateway was 84 feet and the width 42 feet.
