Proverbs 25:8, 28

¶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? [Prov 17:14; Matt 5:25]

Like a city that is broken down and without walls [leaving it unprotected] Is a man who has no self-control over his spirit [and sets himself up for trouble]. [Prov 16:32]
