Ben Sira 19:24-27

24 A devout person, even if he is not very intelligent, is better off than the cleverest of sinners.

25 It is possible to be marvelously clever and still be dishonest, or to get what you want by being absurdly polite.

26 Then there are those wicked people who go about looking very solemn and mournful, but who are only trying to deceive you.

27 They will turn their faces away and pretend not to hear you, but they'll take advantage of you when you least expect it.
