Matthew 2:12-13

But because they were warned in a dream not to go back to Herod, they returned to their country by a different way. After the wise men had left, an angel of the Lord appeared to Joseph in a dream. “Get up!” the angel said. “Take the child and his mother and escape to Egypt! Stay there until I tell you to come back, because Herod is going to try to find the child and kill him.”
