1 John 5:6

He is the one who came by means of water and blood, Yeshua the Messiah — not with water only, but with the water and the blood. And the Spirit bears witness, because the Spirit is the truth. 7 There are three witnesses — 8 the Spirit, the water and the blood — and these three are in agreement. 9 If we accept human witness, God’s witness is stronger, because it is the witness which God has given about his Son.
