Matthew 2:12-15

And being warned of God in a dream that they should not return to Herod, they departed into their own country another way. 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.
