7 But when he saw many of the Pharisees and Sadducees coming to his baptism, he said to them, “Brood of vipers! Who warned you to flee from the wrath to come?
8 Therefore bear fruits worthy of repentance,
9 and do not think to say to yourselves, ‘We have Abraham as our father.’ For I say to you that God is able to raise up children to Abraham from these stones.
10 And even now the ax is laid to the root of the trees. Therefore every tree which does not bear good fruit is cut down and thrown into the fire.
11 I indeed baptize you with water unto repentance, but He who is coming after me is mightier than I, whose sandals I am not worthy to carry. He will baptize you with the Holy Spirit and fire.
12 His winnowing fan is in His hand, and He will thoroughly clean out His threshing floor, and gather His wheat into the barn; but He will burn up the chaff with unquenchable fire.”
The Pharisees and Sadducces were coming to where John was baptizing (v. 7). These religious leaders in their self-righteousness considered themselves acceptable to God. They denied having sin that needed to be confessed or unrighteousness that needed to be forgiven. By virtue of their physical birth, they saw themselves as Abraham’s children, as acceptable to God, and as already members of His kingdom. — Pentecost, page 88

The Pharisees and the Sadducees … came out to John. The Pharisees (the name means a Separatist) were the strictly religious, orthodox-ritualistic class. They were well versed in the traditions of the elders, and occupied themselves with creating new commandments and strange interpretations of the law. They are the fathers of the talmudical Jews of the present day and typical of ritualistic Christendom, having the form of godliness and not the power. The Sadducees were the rationalist, the unbelieving class. They were much given to reform. Their offspring today are the reformed Jews, who reject the greater part of the Word of God, and in Christendom they are remarkably reproduced in the unevangelical “Isms,” though they call themselves “Christian,” who reject portions of the Word, who do not believe in the inspiration of the Bible.
“Offspring of vipers!” thus the Holy Spirit declared through the forerunner their true character. What a strong and cutting word it is, which applies not alone to the Pharisees and Sadducees, but to all ritualistic-religiousness and unbelieving criticism. They are the offspring not of God but of vipers. But still they were the proud boasters of being the seed of Abraham and as such entitled to the promised blessing. They believed that they were to be saved from the wrath of God connected with the establishment of the kingdom, and the wrath would fall entirely upon the Gentile nations. — Gaebelein, pages 68-69

We see a note of urgency in John’s message, for when he called for repentance, he told them that judgment was at hand. He said, “The ax is already at the root of the trees, and every tree that does not produce good fruit will be cut down and thrown into the fire” (v.10). This was in keeping with the Old Testament revelation that the Messiah would come as a Judge and remove the sinful from His kingdom. David in Psalm 24:3 asks rhetorically, “Who may ascend into the hill of the Lord? Who may stand in His holy place?” David meant, Who will be accepted in the Messiah’s kingdom when He comes? The answer is then given: “He who has clean hands and a pure heart, who does not lift up his soul to an idol or swear by what is false” (v.4). Ezekiel 20:34-38 describes this judgment in detail. — Pentecost, page 89.
