Now when they had departed, behold, an angel of the Lord appeared to Joseph in a dream, saying, "Arise, take the young Child and His mother, flee to Egypt, and stay there until I bring you word; for Herod will seek the young Child to destroy Him."  When he arose, he took the young Child and His mother by night and departed for Egypt, and was there until the death of Herod, that it might be fulfilled which was spoken by the Lord through the prophet, saying, "Out of Egypt I called My Son."

Matthew 2:13-15   (NKJV)
