Proverbs 3:30

Contend not with a man without cause, if he hath dealt thee no wrong.

A letting forth of water, is the beginning of strife, therefore, before it breaketh out, abandon, contention.

the lips of a dullard, enter into contention, and his mouth, for blows, crieth out.

Do not go forth to strive in haste, - lest thou know not what to do in the latter end thereof, when thy neighbour, hath put thee to shame.

A man given to anger, stirreth up strife, and, he that exceedeth in wrath, aboundeth in transgression.

But, I, tell you, not to resist evil, - Nay, whoever is smiting thee on the right cheek, turn to him, the other also;

If possible - so far as dependeth on you, with all men being at peace:

But, brother with brother, sueth for judgment, and that before unbelievers?

And, a servant of the Lord, ought not to strive, but to be, gentle, towards all, apt in teaching, ready to endure malice, -
