TSK · Proverbs 29:22

Hatred stirs up dissension, but love covers all transgressions.

A quick-tempered person stirs up dissension, but one who is slow to anger calms a quarrel.

Do not make friends with an angry person, and do not associate with a wrathful person,

As iron sharpens iron, so a person sharpens his friend.

For where there is jealousy and selfishness, there is disorder and every evil practice.
