John 1:29-31

29 The next day John saw Jesus coming to him, and said, "There is the Lamb of God, who takes away the sin of the world!

30 This is the one I was talking about when I said, 'A man is coming after me, but he is greater than I am, because he existed before I was born.'

31 I did not know who he would be, but I came baptizing with water in order to make him known to the people of Israel."
