There were many appearances of angels around the birth of Jesus. His mother Mary was visited by an angel (Gabriel, or Jibril) who told her that she would give birth to the Messiah, the promised One. Angels also appeared to the father of John the Baptist and to Joseph, the man who married Mary. Just after Jesus’ birth, angels appeared to shepherds to announce the good news:
So Joseph also went up from the town of Nazareth in Galilee to Judea, to Bethlehem the town of David, because he belonged to the house and line of David. He went there to register with Mary, who was pledged to be married to him and was expecting a child. While they were there, the time came for the baby to be born, and she gave birth to her firstborn, a son. She wrapped him in cloths and placed him in a manger, because there was no room for them in the inn. And there were shepherds living out in the fields nearby, keeping watch over their flocks at night. An angel of the Lord appeared to them, and the glory of the Lord shone around them, and they were terrified. But the angel said to them, “Do not be afraid. I bring you good news of great joy that will be for all the people. Today in the town of David a Savior has been born to you; he is Christ the Lord. This will be a sign to you: You will find a baby wrapped in cloths and lying in a manger.” Suddenly a great company of the heavenly host appeared with the angel, praising God and saying, “Glory to God in the highest, and on earth peace to men on whom his favor rests.” Luke 2.4-14
Satan did all he could to destroy the baby Jesus. He used the king of Palestine, Herod the Great, to try to kill the baby Jesus. An angel warned Joseph and Mary of this plan, so they went to Egypt to live until Herod was dead. After some time, they were told by an angel to return to Nazareth in Palestine, where Jesus grew up.
