Ezekiel 40:10-13 English Standard Version (ESV)

10. And there were three side rooms on either side of the east gate. The three were of the same size, and the jambs on either side were of the same size.

11. Then he measured the width of the opening of the gateway, ten cubits; and the length of the gateway, thirteen cubits.

12. There was a barrier before the side rooms, one cubit on either side. And the side rooms were six cubits on either side.

13. Then he measured the gate from the ceiling of the one side room to the ceiling of the other, a breadth of twenty-five cubits; the openings faced each other.
