John Trapp on Proverbs 25:9

Verſ. 9. Debate thy cauſe with thy Neighbour, &c.] What ſhall I do then (may ſome ſay) if I may not right my ſelf by law? You may, ſaith he, ſo you do it deliberately: and have firſt privately debated the cauſe out of deſire of agreement, and moved for a compremiſe. See Mat. 18.15.

And diſcover not the ſecret of another] Meerly to be revenged on him for ſome ſuppoſed injury. There are that in their rage care not what they diſcloſe to the prejudice of another. Charity chargeth the contrary, 1 Cor. 13. It claps a plaiſter on the ſore, and then covers it with her hand, as Chirurgions uſe to do, that the world may be never the wiſer.
