Proverbs 17:9

(9) He that covereth a transgression seeketh love—i.e., one who does not notice, but rather conceals and excuses, anything done against him; that man “follows after charity” (1 Corinthians 14:1). (Comp. Proverbs 10:12.)

He that repeateth a matter, who is always returning to old grievances, “alienates (even his) chief friend.”
