There are two places that a woman in Jesus' time would have been - at the well, collecting water, or in the home. Mary had come from a devout family and lived a pure life according to the Lord. She was engaged to be married to Joseph when the angel Gabrielle appeared to Mary.
“Do not be afraid, Mary, for you have found favor with God. And now, you will conceive in your womb and bear a son, and you will name him Jesus. He will be great, and will be called the Son of the Most High, and the Lord God will give to him the throne of his ancestor David. He will reign over the house of Jacob forever, and of his kingdom there will be no end.”
