38 In His teaching He was saying: “Beware of the scribes who like to walk around in long robes, and like respectful greetings in the market places,
39 and chief seats in the synagogues and places of honor at banquets,
40 who devour widows’ houses, and for appearance’s sake offer long prayers; these will receive greater condemnation.” NASB
15 “Beware of the false prophets, who come to you in sheep’s clothing, but inwardly are ravenous wolves.
16 “You will know them by their fruits. Grapes are not gathered from thorn bushes nor figs from thistles, are they?
17 “So every good tree bears good fruit, but the bad tree bears bad fruit.
18 “A good tree cannot produce bad fruit, nor can a bad tree produce good fruit.
19 “Every tree that does not bear good fruit is cut down and thrown into the fire.
20 “So then, you will know them by their fruits. NASB
