But beware of false prophets, which come to you in sheep's clothing, but within are ravening wolves.
By their fruits ye shall know them. Do [men] gather a bunch of grapes from thorns, or from thistles figs?
So every good tree produces good fruits, but the worthless tree produces bad fruits.
A good tree cannot produce bad fruits, nor a worthless tree produce good fruits.
Every tree not producing good fruit is cut down and cast into the fire.
By their fruits then surely a ye shall know b them.
