Pro 17:7 Excellent speech becometh not a fool: much less do lying lips a prince.
Pro 17:8 A gift is as a precious stone in the eyes of him that hath it: whithersoever it turneth, it prospereth.
Pro 17:9 He that covereth a transgression seeketh love; but he that repeateth a matter separateth very friends.
Pro 17:10 A reproof entereth more into a wise man than an hundred stripes into a fool.
Pro 17:11 An evil man seeketh only rebellion: therefore a cruel messenger shall be sent against him.
Pro 17:12 Let a bear robbed of her whelps meet a man, rather than a fool in his folly.
I try to remember verse 9 when I'm angry with my friends. If we love, we forgive, and that breeds more love. If we repeat the offense to all, then we're just upsetting that friend and showing them we are not worth their friendship. Even if we're right, does it really matter?
