Luke 3:2-9

2during the high priesthood of Annas and Caiaphas, the word of God came to John son of Zechariah in the wilderness.

3He went into all the region around the Jordan, preaching a baptism of repentance for the forgiveness of sins, 4as it is written in the book of the words of Isaiah the prophet:

7Then John said to the crowds coming out to be baptized by him, “You brood of vipers, who warned you to flee from the coming wrath? 8Produce fruit, then, in keeping with repentance. And do not begin to say to yourselves, ‘We have Abraham as our father.’ For I tell you that out of these stones God can raise up children for Abraham. 9The axe lies ready at the root of the trees, and every tree that does not produce good fruit will be cut down and thrown into the fire.”
