John 1:29-31

29 On the next day, he saw Yeshua coming to him, and said, "Behold, the Lamb of God, who takes away the sin of the world!
30 This is he of whom I said, 'After me comes a man who is preferred before me, for he was before me.'
31 I didn't know him, but for this reason I came immersing in water: that he would be revealed to Yisra'el."
