'Unsettled' in the Bible

So as for you, do not seek what you will eat and what you will drink; nor have an anxious and unsettled mind.

Peace I leave with you; My [perfect] peace I give to you; not as the world gives do I give to you. Do not let your heart be troubled, nor let it be afraid. [Let My perfect peace calm you in every circumstance and give you courage and strength for every challenge.]

Because we have heard that some without our authorization went out from us and troubled you with their words and unsettled your hearts,

not to be quickly unsettled or alarmed either by a [so-called prophetic revelation of a] spirit or a message or a letter [alleged to be] from us, to the effect that the day of the Lord has [already] come.

but the tongue can no one among men tame; it is an unsettled evil, full of death-bringing poison.

having eyes full of adultery, and who can't cease from sin; enticing unsettled souls; having a heart trained in greed; children of cursing;

as also in all of his letters, speaking in them of these things. In those, there are some things that are hard to understand, which the ignorant and unsettled twist, as they also do to the other Scriptures, to their own destruction.
