Luke 3:7-9

7Then said he to the multitude that came forth to be baptized by him, O generation of vipers, who hath warned you to flee from the wrath to come?

8Bring forth therefore fruits worthy of repentance, and begin not to say within yourselves, We have Abraham for our father: for I say to you, That God is able of these stones to raise up children to Abraham.1

9And now also the axe is laid to the root of the trees: every tree therefore which bringeth not forth good fruit is hewn down, and cast into the fire.
