Matthew 3:7-10 New Revised Standard Version (NRSV)
7 But when he saw many Pharisees and Sadducees coming for baptism, he said to them, “You brood of vipers! Who warned you to flee from the wrath to come? 8 Bear fruit worthy of repentance. 9 Do not presume to say to yourselves, ‘We have Abraham as our ancestor’; for I tell you, God is able from these stones to raise up children to Abraham. 10 Even now the ax is lying at the root of the trees; every tree therefore that does not bear good fruit is cut down and thrown into the fire.
