Thou shalt not hasten with thy mouth, and thy heart shall not be quick to bring forth a word to the face of God: for God is in the heavens, and thou upon the earth: for this thy words shall be few.

Thou shalt not give thy mouth to cause thy flesh to sin; and thou shalt not say to the face of the messenger that it is an error: wherefore shall God be angry at thy voice, and destroy the work of thy hands?

All the labor of man for his mouth, and also the soul shall not be filled.

I am to watch the king's mouth by reason of the oath of God.

The words of the wise one's mouth, grace; and the lips of the foolish one shall swallow him down.

The beginning of the words of his mouth, folly: and the latter state of his mouth the folly of evil.
