John 1:29-31

29 The day after, John sees Jesus coming to him and says, See, here is the Lamb of God who takes away the sin of the world!

30 This is he of whom I said, One is coming after me who is put over me because he was in existence before me.

31 I myself had no knowledge of him, but I came giving baptism with water so that he might be seen openly by Israel.
