What I said was that you make too much of the Ark of the Covenant (with respect to Mary) and the overshadowing. Then I gave Scripture about the Presence of God between the angels over the Mercy Seat. The overshadowing, if we can call it that, was the Mercy Seat, not the Ark of the Covenant, IMO.
Let us compare King David and Lukeās Gospel,
Compare David and the ark to Lukeās account of the Visitation:
In those days Mary arose and went with haste into the hill country, to a city of Judah, and she entered the house of Zechariah and greeted Elizabeth. And when Elizabeth heard the greeting of Mary, the babe leaped in her womb; and Elizabeth was filled with the Holy Spirit and she exclaimed with a loud cry, āBlessed are you among women, and blessed is the fruit of your womb! And why is this granted me, that the mother of my Lord should come to me? For behold, when the voice of your greeting came to my ears, the babe in my womb leaped for joy. And blessed is she who believed that there would be a fulfillment of what was spoken to her from the Lordā (Luke 1:39ā45).
Mary arose and went to the hill country of Judea. I have been to both Ein Kerem (where Elizabeth lived) and Abu Ghosh (where the ark resided), and they are only a short walk apart. Mary and the ark were both on a journey to the same hill country of Judea.
When David saw the ark he rejoiced and said, āHow can the ark of the Lord come to me?ā Elizabeth uses almost the same words: āWhy is this granted me, that the mother of my Lord should come to me?ā Luke is telling us somethingādrawing our minds back to the Old Testament, showing us a parallel.
When David approached the ark he shouted out and danced and leapt in front of the ark. He was wearing an ephod, the clothing of a priest. When Mary, the Ark of the New Covenant, approached Elizabeth, John the Baptist leapt in his motherās wombāand John was from the priestly line of Aaron. Both leapt and danced in the presence of the ark. The Ark of the Old Covenant remained in the house of Obed-edom for three months, and Mary remained in the house of Elizabeth for three months. The place that housed the ark for three months was blessed, and in the short paragraph in Luke, Elizabeth uses the word blessed three times. Her home was certainly blessed by the presence of the ark and the Lord within.
When the Old Testament ark arrivedāas when Mary arrivedāthey were both greeted with shouts of joy. The word for the cry of Elizabethās greeting is a rare Greek word used in connection with Old Testament liturgical ceremonies that were centered around the ark and worship (cf. Word Biblical Commentary, 67). This word would flip on the light switch for any knowledgeable Jew.
The ark returns to its home and ends up in Jerusalem, where Godās presence and glory is revealed in the temple (2 Sam. 6:12; 1 Kgs. 8:9ā11). Mary returns home and eventually ends up in Jerusalem, where she presents God incarnate in the temple (Luke 1:56; 2:21ā22).
