John 1:29-31

29 On the morrow John sees Jesus coming to him, and he says, Behold, the Lamb of God who takes away the sin of the world!

30 This is he about whom I said, After me comes a man who has become before me, because he was before me.

31 And I had not known him, but that he would be made known to Israel. Because of this I came immersing in water.
