John 1:26-34 New Revised Standard Version Catholic Edition (NRSVCE)
26 John answered them, “I baptize with water. Among you stands one whom you do not know, 27 the one who is coming after me; I am not worthy to untie the thong of his sandal.” 28 This took place in Bethany across the Jordan where John was baptizing.
The Lamb of God
29 The next day he saw Jesus coming toward him and declared, “Here is 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 ranks ahead of me because he was before me.’ 31 I myself did not know him; but I came baptizing with water for this reason, that he might be revealed to Israel.” 32 And John testified, “I saw the Spirit descending from heaven like a dove, and it remained on him. 33 I myself did not know him, but the one who sent me to baptize with water said to me, ‘He on whom you see the Spirit descend and remain is the one who baptizes with the Holy Spirit.’ 34 And I myself have seen and have testified that this is the Son of God.”[a]
