Lips that speak knowledge are a rare jewel

Proverbs 20:1-30
It is a man's honor to avoid strife.
Many a man claims to have unfailing love, but a faithful man who can find?
The righteous man leads a blameless life; blessed are his children after him. -- When I do the righteous things, blessing will be on my children, don't worry about them.
Gold there is and rubies in abundance, but lips that speak knowledge are a rare jewel.
A gossip betrays a confidence; so avoid a man who talks too much.
Do not say, "I'll pay you back for this wrong!" Wait for the Lord, and he will deliver you.
The Lord detests differing weights, and dishonest scales do not please him.
The lamp of the Lord searches the spirit of a man; it searches out his inmost being.
Blows and wounds cleanse away evil, and beatings purge the inmost being.
Why?
Strife and quarrel should away it, it is meaningless and is trouble, to gain man's honor. To be a prudent and noble man.
Avoid a man who talk too much, away from quarrel and gossip. work diligent  and pursue righteous, blessing comes.
Revenge work is belong to the Lord, don't even say I will pay back the wrong.
Cheating and dishonest are detested by the Lord, to be a honest man even lost benefit. The Lord search the spirit of a man, no one can hide from the Lord. inmost being will be seen from the Lord.
How?
Lips that speak knowledge are a rare jewel. I hope I can speak knowledge in the right time. Pray to the Lord has this gift.
