Ben Sira 11:9

9 Do not argue about a matter which does not concern you, nor sit with sinners when they judge a case.

Ben Sira 11:9 In-Context

7 Do not find fault before you investigate; first consider, and then reprove.

8 Do not answer before you have heard, nor interrupt a speaker in the midst of his words.

9 Do not argue about a matter which does not concern you, nor sit with sinners when they judge a case.

10 My son, do not busy yourself with many matters; if you multiply activities you will not go unpunished, and if you pursue you will not overtake, and by fleeing you will not escape.

11 There is a man who works, and toils, and presses on, but is so much the more in want.
