Coptic:
I understand your interpretation, but do not agree, because I see no evidence/proof of it. But it is a beautiful idea.
Psalm 40, 5 says God hath sanctified his own tabernacle. God purified His tabernacle because His Body (Jesus) was to dwell in the tabernacle. This is a foreshadowing of Mary, the new Ark of the Covenant.
The angel told Mary, “The Holy Spirit shall come upon thee, and the power of the most high shall overshadow thee…” (Luke 1, 35). This is the same language in Exodus 40, 31-34. When Moses dedicated the Ark of the Covenant “the power of the most high descended upon the ark.”
Exodus 25 describes how the Old Testament Ark had to be made in a particular way. This is because it was a type of Mary. Golden rings were to be made into the ark, so that it could be carried with poles, since no one could touch the ark. Sin (sinful men) could not touch the ark, or they would be dead. Numbers Chapter 4 says you cannot even look inside the ark or you would die.
The Ark was a source of power for the Israelites. They won their battles when they had the Ark with them. And when they lost the Ark, 1Samuel (Kings) 5 says the Israelites lost their glory (power).
1 Samuel 6 describes how the Philistines started dying because of the Ark, which they had stolen. Their stone god kept falling over until the head was broken (head crushed). Then, in 1 Samuel 7, the Ark was returned to Israel, because the Philistines realized the power of the Ark.
David called for Ark of the Covenant to be brought to him. While on the way to Jerusalem on the back of oxen, the Ark rocked like it would fall to the ground. In an effort to steady the Ark, the priest reached his hand out and touched the Ark. God struck him dead. Why would God kill the priest for trying to take care of the Ark? They were not told the Ark couldn’t touch the ground, but rather, it could not be touched by sinful man. The Ark was absolutely untouched by sin.
What made the Ark so important and powerful? It contained The Word of God, and the manna, (as well as the rod of Aaron that budded). What did Mary have in her womb? The Word of God (Jesus), who describes himself as the manna come down from heaven. At the dedication, the power of God came down upon the Ark. In a like manner, Mary, the new Ark of the Covenant, was overshadowed by the power of God, and the Word dwelt in her.
David realized the power of the Ark in the death of the priest, and sent the Ark of the Covenant away, where it stayed for three months. Likewise, Mary went away to stay with Elizabeth, also for three months.
When Mary came to Elizabeth, notice what Elizabeth says to Mary; “Who am I that the Mother of my Lord should come to me?” (Luke 1; 43) This is just what David said in regard to the Ark, “Who am I that the Ark of the Covenant should come to me?”
When Mary came to Elizabeth, something else happened as well. The child leapt in Elizabeth’s womb. What did David do when the Ark came to him? He leapt and danced before the Ark (2 Kings (Samuel) 6, 14-15).
The parallel is unmistakable. Mary is the fulfillment of the Old Testament Ark of the Covenant.
We might do well to notice that Michel (David’s wife) frowned on David’s rejoicing before the Ark and was punished by never having another child. We should be careful what we say about the new Ark of the Covenant.
Some people might assert that the rejoicing of John the Baptist in the womb of Elizabeth is attributed to Jesus in Mary’s womb, not Mary at all. In a sense this is true but this scripture is not emphasizing that point. The rejoicing is upon Mary’s greeting, (when Elizabeth “heard” the greeting of Mary), not upon Mary’s entering the house. And the response is “blessed are you…and…blessed is…Jesus.” The response was not “who am I that my Lord should come to me”. Rather, it was “who am I that the mother of my Lord should come to me”. And it continues “for as soon as I heard your voice…” Again the emphasis is on Mary.
Recognizing Mary as the new Ark of the Covenant, and that as such, she could not be touched by sin (that is to say she was sinless), helps us to understand other Marian Doctrines. God sanctified Mary at the instant of her conception, so that His tabernacle would be pure.
