TSK · Proverbs 18:6

A fool’s annoyance is known at once, but the prudent conceals dishonor.

In the speech of a fool is a rod for his back, but the words of the wise protect them.

A wicked scoundrel digs up evil, and his slander is like a scorching fire.

Starting a quarrel is like letting out water; abandon strife before it breaks out!

Penalties have been prepared for scorners, and floggings for the backs of fools.

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

A stone is heavy and sand is weighty, but vexation by a fool is more burdensome than the two of them.
