Psalm 39

Psalmist says, I will guard my ways lest I sin with my tongue.

From adw blog:
Some of the most common sins we commit are related to speech: gossip, idle chatter, lies, exaggerations, harsh attacks, and uncharitable remarks. With our tongue we can spread hatred, incite fear and maliciousness, spread misinformation, cause temptation, discourage, teach error, and ruin reputations. With a gift capable of bringing such good, we can surely cause great harm!

For we all stumble in many things. If anyone does not stumble in word, he is a perfect man, able also to bridle the whole body.
James 3:2 NKJV

Muzzle:

Is good enough to let air go in, but stop biting others or licking own wounds

Isaiah 6: 1- 7
Man of unclean lips
I dwell among people who people who have unclean lips.

When you hide your intense feelings you burst out.

But speak to God.

Every man at it's best is Vapor.

David's acknowledgement of his son is the greatest character.

We say sorry Lord for our sins, but David cries with tears.
