My lips shall not speak wickedness, nor my tongue utter deceit.

For my mouth shall speak truth; and wickedness is an abomination to my lips.

All the words of my mouth are in righteousness; there is nothing froward or perverse in them.

For our exhortation was not of deceit, nor of uncleanness, nor in guile:

But as we were allowed of God to be put in trust with the gospel, even so we speak; not as pleasing men, but God, which trieth our hearts.

Should a wise man utter vain knowledge, and fill his belly with the east wind?

I will fetch my knowledge from afar, and will ascribe righteousness to my Maker.

For truly my words shall not be false: he that is perfect in knowledge is with thee.

Who is this that darkeneth counsel by words without knowledge?

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

The law of his God is in his heart; none of his steps shall slide.

The tongue of the wise useth knowledge aright: but the mouth of fools poureth out foolishness.

The lips of the wise disperse knowledge: but the heart of the foolish doeth not so.

There is gold, and a multitude of rubies: but the lips of knowledge are a precious jewel.
