We pray the "Hail Mary"- as each Verse of that prayer IS IN THE BIBLE - for the Blessed Virgin to Pray FOR us sinners, until we die.... Ummm...no, it's not. The angel Gabriel appeared to Mary to announce she would be the Christ bearer:
In the sixth month, God sent the angel Gabriel to a town in Galilee called Nazareth, to a virgin pledged in marriage to a man named Joseph, who was of the house of David. And the virgin’s name was Mary. The angel appeared to her and said, “Greetings, you who are highly favored! The Lord is with you.” Mary was greatly troubled at his words and wondered what kind of greeting this might be. So the angel told her, “Do not be afraid, Mary, for you have found favor with God. Behold, you will conceive and give birth to a son, and you are to give Him the name Jesus. He will be great and will be called the Son of the Most High. The Lord God will give Him the throne of His father David, and He will reign over the house of Jacob forever. His kingdom will never end!” “How can this be,” Mary asked the angel, “since I am a virgin?” The angel replied, “The Holy Spirit will come upon you, and the power of the Most High will overshadow you. So the Holy One to be born will be called the Son of God. Look, even Elizabeth your relative has conceived a son in her old age, and she who was called barren is in her sixth month. For no word from God will ever fail.” “I am the Lord’s servant,” Mary answered. “May it happen to me according to your word.” Then the angel left her.
And Mary arose in those days, and went into the hill country with haste, into a city of Juda; And entered into the house of Zacharias, and saluted Elisabeth. And it came to pass, that, when Elisabeth heard the salutation of Mary, the babe leaped in her womb; and Elisabeth was filled with the Holy Ghost: And she spake out with a loud voice, and said, Blessed art thou among women, and blessed is the fruit of thy womb. And whence is this to me, that the mother of my Lord should come to me? For, lo, as soon as the voice of thy salutation sounded in mine ears, the babe leaped in my womb for joy. And blessed is she that believed: for there shall be a performance of those things which were told her from the Lord.(Luke 1:26-45)
Maybe you can parse some words together from Gabriel and Elisabeth's greetings to Mary (it wasn't a "prayer") for the first half of the Catholic prayer to Mary (the Hail Mary), but the second part is all fabricated and not "IN THE BIBLE". Besides, we direct our prayers to God alone.
For mine own sake, even for mine own sake, will I do it: for how should my name be polluted? and I will not give my glory unto another. (Isaiah 48:11)
