The Closed Gate
A gate toward the east that no one opens, and the Lord passing through it. Scroll to watch it.
The gate which looks towards the East shall be closed, and shall not be opened, and no one shall pass through it, because the Lord God of Israel shall pass through it, and it shall be closed.
Ezekiel 44:2, as Rufinus gives it
the prophet declares, "the Lord, the God of Israel, hath entered in and gone out, and the gate remaineth closed." If, moreover, the Word was made flesh without sexual intercourse, being conceived altogether without seed, then was He born without injury to her virginity.
Cyril of Alexandria, Commentary on Luke Sermon 1
