Ezekiel 40:9-11

9He measured the porch of the gate, eight cubits; and its side pillars, two cubits. And the porch of the gate was 1faced inward.

10The 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.

11And he measured the width of the 2gateway, ten cubits, and the length of the gate, thirteen cubits.
