'Quietness' in the Bible

Better is a dry morsel and quietness with itThan a house full of feasting with strife.

The words of the wise heard in quietness are better than the shouting of a ruler among fools.

For thus the Lord God, the Holy One of Israel, has said,“In repentance and rest you will be saved,In quietness and trust is your strength.”But you were not willing,

And the work of righteousness will be peace,And the service of righteousness, quietness and confidence forever.
