Matthew 2:12-13

But God warned them in a dream not to go back to Herod. So they returned to their country on a different road. When the Wise Men had left, Joseph had a dream. In the dream an angel of the Lord appeared to Joseph. “Get up!” the angel said. “Take the child and his mother and escape to Egypt. Stay there until I tell you to come back. Herod is going to search for the child. He wants to kill him.”
