1 Samuel 24:9

Also take no heed unto all words that are spoken; lest thou hear thy servant curse thee: For oftentimes also thine own heart knoweth that thou thyself likewise hast cursed others.

If a ruler hearken to lies, all his servants are wicked.

Now therefore, I pray thee, let my lord the king hear the words of his servant. If the Lord have stirred thee up against me, let him accept an offering: but if they be the children of men, cursed be they before the Lord; for they have driven me out this day from abiding in the inheritance of the Lord, saying, Go, serve other gods.

And the tongue is a fire, a world of iniquity: so is the tongue among our members, that it defileth the whole body, and setteth on fire the course of nature; and it is set on fire of hell.

Thou shalt not go up and down as a talebearer among thy people: neither shalt thou stand against the blood of thy neighbour: I am the Lord.

A froward man soweth strife: and a whisperer separateth chief friends.

A wicked doer giveth heed to false lips; and a liar giveth ear to a naughty tongue.

The words of a talebearer are as wounds, and they go down into the innermost parts of the belly.

The north wind driveth away rain: so doth an angry countenance a backbiting tongue.

Where no wood is, there the fire goeth out: so where there is no talebearer, the strife ceaseth. As coals are to burning coals, and wood to fire; so is a contentious man to kindle strife. The words of a talebearer are as wounds, and they go down into the innermost parts of the belly.

A lying tongue hateth those that are afflicted by it; and a flattering mouth worketh ruin.

Whoso privily slandereth his neighbour, him will I cut off: him that hath an high look and a proud heart will not I suffer.

When their judges are overthrown in stony places, they shall hear my words; for they are sweet.
