Matthew 2:12-16

Then they returned to their country by another road, since God had warned them in a dream not to go back to Herod. After they had left, an angel of the Lord appeared in a dream to Joseph and said, “Herod will be looking for the child in order to kill him. So get up, take the child and his mother and escape to Egypt, and stay there until I tell you to leave.” Joseph got up, took the child and his mother, and left during the night for Egypt, where he stayed until Herod died. This was done to make what the Lord had said through the prophet come true, “I called my Son out of Egypt.” When Herod realized that the visitors from the east had tricked him, he was furious. He gave orders to kill all the boys in Bethlehem and its neighbourhood who were two years old and younger — this was done in accordance with what he had learned from the visitors about the time when the star had appeared.
