With regard to God's indwelling in the Virgin during the Incarnation, the Church calls her the Second Heaven and the Tabernacle or the Dome of Moses.
The Church also calls the Virgin the City of God or Zion, as it is said in the psalm: "And of Zion it will be said, 'This one and that one were born in her; and the Most High Himself shall establish her"' and "Glorious things are spoken of you, 0 city of God!" (Ps. 87)
Since the Lord Jesus said that He resembles the manna because He is the Living Bread that came down from heaven (John.6: 58), therefore, the Church calls the Virgin the Manna Pot.
Regarding St. Mary's virginity, the Church calls her Aaron's Rod which blossomed (Num.17).
