'Tranquility' in the Bible

The Lord lift up His countenance (face) upon you [with divine approval],And give you peace [a tranquil heart and life].’

For length of days and years of life [worth living]And tranquility and prosperity [the wholeness of life’s blessings] they will add to you.

A heart of tranquility [is] life [to the] flesh, but causes bones of passion to rot.

It's better to have one handful of tranquility than to have two handfuls of trouble and to chase after the wind.

Therefore, your majesty, may my advice be acceptable to you: Stop your sinning, do what's right, and put a stop to your wickedness by showing kindness to the oppressed. Perhaps your tranquility will continue."

""In his place there will arise a despicable person, upon whom no royal authority has been conferred, but he'll invade in a time of tranquility, taking over the kingdom through deception.

He'll invade the most prosperous areas of the province during a time of tranquility, accomplishing what neither his predecessors nor his ancestors ever could. He'll distribute war spoils, booty, and wealth to them, and he'll plot the overthrow of fortresses, though only for a time.
