I think Scripture’s depiction of Mary as the New Ark of the Covenant best describes her bodily entrance into Heaven.
Psalm 132:8 says, “rise, O LORD, to Your resting place,You and the ark of Your strength.”
Now this is a clear reference from 2 Chronicles 6:41, but once you pick apart how all those things are fulfilled in the New Covenant, Mary’s Assumption becomes clear.
Lord - God’s presence within the Ark of the Covenant
Resting Place - The Tabernacle (which was modeled after the tabernacle in Heaven
Ark - Gold Box containing the 10 commandments, a jar of manna (“bread from heaven”), and Aaron’s priestly staff.
Lord - Jesus, in the flesh
Resting Place - Heaven Itself (particularly the Heavenly tabernacle)
Ark - Mary, who bore in her the fulfillment of the law, the true bread come from heaven, and the eternal high priest.
Also, even though he didn’t explicitly mention it, St. Gregory Thaumaturgus cited the very Psalm I mentioned above with Mary, and he died in 270 A.D.!
“Let us chant the melody which has been taught us by the inspired harp of David, and say, ‘Arise, O Lord, into Thy rest; Thou, and the Ark of Thy sanctuary.’ For the holy Virgin is in truth an Ark, wrought with gold both within and without, that has received the whole treasury of the sanctuary" ~St. Gregory Thaumaturgus
