Matthew 3:7-9

But when he saw many of the Pharisees and Sadducees coming for baptism, he said to them, “You brood of vipers, who warned you to flee from the wrath to come? Therefore bear fruit in keeping with repentance; and do not suppose that you can say to yourselves, ‘We have Abraham for our father’; for I say to you that from these stones God is able to raise up children to Abraham.
