Ezekiel 40:36-38

Amplified Bible

³⁶ with its guardrooms, its side pillars, its porches; and the gate had windows all around. The length was fifty cubits and the width was twenty-five cubits. ³⁷ Its side pillars faced the outer courtyard, and palm tree decorations were [carved] on them on either side. And its stairway had eight steps.

³⁸ A chamber with its doorway was by the side pillars of the gates; there the burnt offering was to be washed.
