⁴ as it is written in the book of the words of the prophet Isaiah,

³ This is the one of whom the prophet Isaiah spoke when he said,

²⁸ You yourselves are my witnesses that I said, ‘I am not the Messiah,^[a] but I have been sent ahead of him.’^{(A) 29} He who has the bride is the bridegroom. The friend of the bridegroom who stands and hears him rejoices greatly at the bridegroom’s voice. For this reason my joy has been fulfilled.^{(B) 30} He must increase, but I must decrease.”^[b]

The One Who Comes from Heaven

³¹ The one who comes from above is above all; the one who is of the earth belongs to the earth and speaks about earthly things. The one who comes from heaven is above all.^{(C) 32} He testifies to what he has seen and heard, yet no one accepts his testimony.^{(D) 33} Whoever has accepted his testimony has certified^[c] this, that God is true.^{(E) 34} He whom God has sent speaks the words of God, for he gives the Spirit without measure.^{(F) 35} The Father loves the Son and has placed all things in his hands.^{(G) 36} Whoever believes in the Son has eternal life; whoever disobeys the Son will not see life but must endure God’s wrath.^(H)

The Testimony of John the Baptist

¹⁹ This is the testimony given by John when the Jews sent priests and Levites from Jerusalem to ask him, “Who are you?” ²⁰ He confessed and did not deny it, but he confessed, “I am not the Messiah.”^{[a](A) 21} And they asked him, “What then? Are you Elijah?” He said, “I am not.” “Are you the prophet?” He answered, “No.”^{(B) 22} Then they said to him, “Who are you? Let us have an answer for those who sent us. What do you say about yourself?” ²³ He said,

as the prophet Isaiah said.^(C)

²⁴ Now they had been sent from the Pharisees. ²⁵ They asked him, “Why, then, are you baptizing if you are neither the Messiah,^[b] nor Elijah, nor the prophet?” 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 strap 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!^{(D) 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.^{(E) 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.’^{(F) 34} And I myself have seen and have testified that this is the Chosen One.”^[c]

¹⁵ (John testified to him and cried out, “This was he of whom I said, ‘He who comes after me ranks ahead of me because he was before me.’ ”)
