Luke 3:9; Luke 6:43; Luke 6:44; Luke 13:19

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

43 For a good tree bringeth not forth corrupt fruit; neither doth a corrupt tree bring forth good fruit.

44 For every tree is known by his own fruit. For of thorns men do not gather figs, nor of a bramble bush gather they grapes.

19 It is like a grain of mustard seed, which a man took, and cast into his garden; and it grew, and waxed a great tree; and the fowls of the air lodged in the branches of it.
