Proverbs 25:8-10

Amplified Bible

⁸ 
Do not rush out to argue your case [before magistrates or judges];
Otherwise what will you do in the end [when your case is lost and]
When your neighbor (opponent) humiliates you?^(A)
9 
Argue your case with your neighbor himself [before you go to court];
And do not reveal another’s secret,^(B)
10 
Or he who hears it will shame you
And the rumor about you [and your action in court] will have no end.
