Ezekiel 40:6-10

Then he went to the gate which faced east, went up its steps, and measured the threshold of the gate, one rod in width; and the other threshold was one rod in width.

The guardroom was one rod long and one rod wide; and there were five cubits between the guardrooms. And the threshold of the gate by the porch of the gate facing inward was one rod.

Then he measured the porch of the gate facing inward, one rod.

And he measured the porch of the gate, eight cubits; and its side pillars, two cubits. And the porch of the gate was faced inward.

The guardrooms of the gate toward the east numbered three on each side; the three of them had the same measurement. The side pillars also had the same measurement on each side.
