Proverbs 11:12

He who despises his neighbor lacks a heart of wisdom,

But a man of discernment keeps silent.

Proverbs 12:18

There is one who speaks rashly like the thrusts of a sword,

But the tongue of the wise brings healing.

A tongue that brings healing is a tree of life,

But perversion in it breaks the spirit.

A vile man digs up evil,

And the words on his lips are like scorching fire.

The north wind brings forth rain,

And a tongue of secrets, an indignant face.

Like a sparrow in its flitting, like a swallow in flying,

So a curse without cause does not come to pass.
