Proverbs 15:7

O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh.

Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.

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.

The mouth of the righteous speaketh wisdom, and his tongue talketh of judgment.

With my lips have I declared all the judgments of thy mouth.

What I tell you in darkness, that speak ye in light: and what ye hear in the ear, that preach ye upon the housetops.

And he said unto them, Go ye into all the world, and preach the gospel to every creature.

Thou art fairer than the children of men: grace is poured into thy lips: therefore God hath blessed thee for ever.

Thy lips, O my spouse, drop as the honeycomb: honey and milk are under thy tongue; and the smell of thy garments is like the smell of Lebanon.

And the things that thou hast heard of me among many witnesses, the same commit thou to faithful men, who shall be able to teach others also.
