Ezekiel 40:15

15. Plumptre points out that the whole length of the gate, from the outer entrance to the inner exit, was thus composed: 1. An outer threshold (Ezekiel 40:6), 6 cubits; 2. Three guard chambers (Ezekiel 40:7), 18 cubits; 3. Two spaces between chambers (Ezekiel 40:11), 10 cubits; 4. An inner threshold (Ezekiel 40:7), 6 cubits; 5. A porch before the gate (Ezekiel 40:9), 8 cubits; 6. One post or pillar (Ezekiel 40:10), 2 cubits; total, 50 cubits. It will be remembered that these were sacred cubits, each being equal to seven hand-breadths (Ezekiel 40:5).
