Matthew 2:12-13

And having been warned [by God] in a dream not to go back to Herod, the magi left for their own country by another way. Now when they had gone, an angel of the Lord appeared to Joseph in a dream and said, “Get up! Take the Child and His mother and flee to Egypt, and remain there until I tell you; for Herod intends to search for the Child in order to destroy Him.”
