Matthew 2:13-15

Now when they were departed, behold, an angel of the Lord appeareth to Joseph in a dream, saying, Arise and take the young child and his mother, and flee into Egypt, and be thou there until I tell thee: for Herod will seek the young child to destroy him. And he arose and took the young child and his mother by night, and departed into 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 did I call my son.
