An angel of the Lord

Now when they had departed, behold, an angel of the Lord appeared to Joseph in a dream, saying, “Arise and take the young child and his mother, and flee into Egypt, and stay there until I tell you, for Herod will seek the young child to destroy him.” 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 I called my son.”

Matthew 2:13-15

An angel of the Lord appears to Joseph in a dream and tells him to take the child and his mother to Egypt.
