Ben Sira 19:26

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

Ben Sira 19:26 In-Context

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.

28 If for some reason they are unable to sin now, they'll get around to it at the first opportunity.
