It’s easy to miss the parallel between the Holy Spirit overshadowing the ark and the Holy Spirit overshadowing Mary, between the Ark of the Old Covenant as the dwelling place of God and Mary as the new dwelling place of God.
God was very specific about every exact detail of the ark (Ex. 25–30). It was a place where God himself would dwell (Ex. 25:8). God wanted his words—inscribed on stone—housed in a perfect container covered with pure gold within and without. How much more would he want his Word—Jesus—to have a perfect dwelling place! If the only begotten Son were to take up residence in the womb of a human girl, would he not make her flawless?
The Virgin Mary is the living shrine of the Word of God, the Ark of the New and Eternal Covenant. In fact, St. Luke’s account of the annunciation of the angel to Mary nicely incorporates the images of the tent of meeting with God in Sinai and of the temple of Zion. Just as the cloud covered the people of God marching in the desert (cf. Num. 10:34; Deut. 33:12; Ps. 91:4) and just as the same cloud, as a sign of the divine mystery present in the midst of Israel, hovered over the Ark of the Covenant (cf. Ex. 40:35), so now the shadow of the Most High envelops and penetrates the tabernacle of the New Covenant that is the womb of Mary (cf. Luke 1:35) (Pontifical Council for the Pastoral Care of Migrants and Itinerant People, The Shrine: Memory, Presence and Prophecy of the Living God).
Luke weaves additional parallels into the story of Mary—types that could be overlooked if one is unfamiliar with the Old Testament. After Moses died, Joshua led the Israelites across the Jordan River into the Promised Land. Joshua established the Ark of the Covenant in Shiloh, where it stayed for more than 200 years. One day the Israelites were losing a battle with the Philistines, so they snatched the ark and rushed it to the front lines. The Philistines captured the ark, but it caused them great problems, so they sent it back to Israel (1 Sam. 5:1–6:12).
David went out to retrieve the ark (1 Sam 6:1–2). After a man named Uzzah was struck dead when he touched the ark, David was afraid and said, “How can the ark of the Lord come to me?” He left the ark in the hill country of Judea for three months. We are also told that David danced and leapt in front of the ark and everyone shouted for joy. The house of Obed-edom, which had housed the ark, was blessed, and then David took the ark to Jerusalem (2 Sam. 6:9–14).
Compare David and the ark to Luke’s 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, “Blessed 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 Lord” (Luke 1:39–45).
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, “How can the ark of the Lord come to me?” Elizabeth uses almost the same words: “Why is this granted me, that the mother of my Lord should come to me?” Luke is telling us something—drawing 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 mother’s womb—and 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 arrived—as when Mary arrived—they were both greeted with shouts of joy. The word for the cry of Elizabeth’s 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 God’s presence and glory is revealed in the temple (2 Sam. 6:12; 1 Kgs. 8:9–11). Mary returns home and eventually ends up in Jerusalem, where she presents God incarnate in the temple (Luke 1:56; 2:21–22).
