I know this.She is not the character in the Nativity scene we put in the yard every year for Christmas,then pack away.
She is prefigured in the OT as the Ark of the Covenant. Read 2nd Samuel 6 and d Luke 1:39.Then we find even more scripture to compare:
In Luke 1:35, the angel Gabriel tells Mary "The Holy Spirit will come upon you, and the power of the Most High will overshadow you." Now, the Greek word for "overshadow" is episkiasei, which denotes a bright cloud of glory. It is the same cloud at the transfiguration of Jesus (Matthew 17:5, Mark 9:7. Luke 9:34), and it is known as the Shekinah Glory - the visible Presence of God in the Hebrew Scriptures - which dwelt in the Holy of Holies above the ark of the covenant (Exodus 24:15-16, 40:34-38, 1 Kings 8:10).Source: http://www.angelfire.com/ok3/apologia/saintbenedict/maryark.html
For a complete listing of ALL scripture renderings re Mary as the Ark of the Covenant I HIGHLY recommend AGAPE BIBLE STUDY
My soul magnifies the Lord And my spirit rejoices in God my Savior; Because He has regarded the lowliness of His handmaid; For behold, henceforth all generations shall call me blessed; Because He who is mighty has done great things for me, and holy is His name; And His mercy is from generation to generation on those who fear Him. He has shown might with His arm, He has scattered the proud in the conceit of their heart. He has put down the mighty from their thrones, and has exalted the lowly. He has filled the hungry with good things, and the rich He has sent away empty. He has given help to Israel, his servant, mindful of His mercy Even as he spoke to our fathers, to Abraham and to his posterity forever.
