Ezekiel 40:28-31

Ezekiel discovered that the south inner gate complex was the same as the outer gate complexes. All the vestibules of the three gate complexes totaled 25 cubits (41 feet 8 inches) across and each of them was five cubits deep (rather than eight, 8 feet 4 inches rather than 13 feet 4 inches, Ezekiel 40:9). Also there were windows or niches on all four sides and eight steps leading up to it from the outer court (cf. Ezekiel 40:22). However the vestibule of this gate complex, as well as the other inner gate complexes, was facing the outer court.
