Matthew 1:20-21; Acts 8:26

20 But as he considered these things, behold, an angel of the Lord appeared to him in a dream, saying, "Joseph, son of David, do not fear to take Mary as your wife, for that which is conceived in her is from the Holy Spirit. 21 She will bear a son, and you shall call his name Jesus, for he will save his people from their sins."
26 Now an angel of the Lord said to Philip, "Rise and go toward the south to the road that goes down from Jerusalem to Gaza." This is a desert place.
