Matthew 1:20-21 (NIV)
20 But after he had considered this, an angel of the Lord appeared to him in a dream and said, “Joseph son of David, do not be afraid to take Mary home as your wife, because what is conceived in her is from the Holy Spirit.
21 She will give birth to a son, and you are to give him the name Jesus, because he will save his people from their sins.”
Revelation 2:17 (NIV)
17 He who has an ear, let him hear what the Spirit says to the churches. To him who overcomes, I will give some of the hidden manna. I will also give him a white stone with a new name written on it, known only to him who receives it.
