Ben Sira 19:13

13 If you hear that a friend has done something wrong, ask him about it. Maybe it isn't true. If it is true, he won't do it again.

Ben Sira 19:13 In-Context

11 A foolish person trying to keep a secret suffers like a woman in labor.
12 Any time he hears a secret, it's like an arrow stuck in his leg.
13 If you hear that a friend has done something wrong, ask him about it. Maybe it isn't true. If it is true, he won't do it again.
14 If you hear that a neighbor has said something he shouldn't, ask him about it. Maybe he didn't say it. If he did, he won't say it again.
15 If you hear something bad about a friend, ask him about it. It might be a lie. Don't believe everything you hear.
