Proverbs 17:14 King James Version (KJV)
14 The beginning of strife is as when one letteth out water: therefore leave off contention, before it be meddled with.
Proverbs 18:17-19 King James Version (KJV)
17 He that is first in his own cause seemeth just; but his neighbour cometh and searcheth him.
18 The lot causeth contentions to cease, and parteth between the mighty.
19 A brother offended is harder to be won than a strong city: and their contentions are like the bars of a castle.
