“I baptize you

With water

For repentance.

But one,

Who is more powerful

Than I,

Is coming after me.

I am not worthy

To carry his sandals.

He will baptize you

With the Holy Spirit,

And with fire.”

ἐγὼ μὲν ὑμᾶς βαπτίζω ἐν ὕδατι εἰς μετάνοιαν· ὁ δὲ ὀπίσω μου ἐρχόμενος ἰσχυρότερός μού ἐστιν, οὗ οὐκ εἰμὶ ἱκανὸς τὰ ὑποδήματα βαστάσαι· αὐτὸς ὑμᾶς βαπτίσει ἐν Πνεύματι Ἁγίῳ καὶ πυρί·

The wording here is the same as in Mark, chapter 1:7-8 and Luke, chapter 3:16-17, indicating a common source. However, in Luke, John the Baptist was responding to questions about whether he was the Messiah. Instead, John said that he was anticipating a messianic figure greater than himself. He was the precursor or forerunner of Jesus, so that sometimes he was also identified with the prophet Elijah. John the Baptist was clear in this utterance (ἐγὼ μὲν). He baptized in water for repentance (βαπτίζω ἐν ὕδατι εἰς μετάνοιαν). However, after him (ὁ δὲ ὀπίσω μου), there would be a messianic one more powerful than him (ἐρχόμενος ἰσχυρότερός μού ἐστιν,). He felt that he was not fit or worthy to carry his sandals (οὗ οὐκ εἰμὶ ἱκανὸς τὰ ὑποδήματα βαστάσαι). This one to come was going to baptize them (αὐτὸς ὑμᾶς βαπτίσει) in the Holy Spirit (ἐν Πνεύματι Ἁγίῳ) and fire (καὶ πυρί). Mark, chapter 1:8, also said that the one to come would baptize with the Holy Spirit, did not mention any fire. This is the second mention of the Holy Spirit in Matthew since he was also the originator of Jesus in the womb of Mary. Now he was going to use purifying fire in the baptismal washing.
