I asked a lawyer who visits prisoners at least twice a week, and he gave me a few verses.
Thanks to Bob.
John 14:27
Peace I leave with you; my peace I give to you. Not as the world gives do I give it to you. Do not let your hearts be troubled or afraid.
Matt 11:28-30
"Come to me, all you who labor and are burdened, and I will give you rest. Take my yoke upon you and learn from me, for I am meek and humble of heart; and you will find rest for your selves. For my yoke is easy, and my burden light.”
2 Tim 1:7
For God did not give us a spirit of cowardice but rather of power and love and self-control.
Is 26:3
"With firm purpose you maintain peace; in peace, because of our trust in you.”
And here’s a couple I found that you may like:
Dt 31:6
"Be strong and courageous. Do not be afraid or terrified because of them, for the Lord your God goes with you; he will never leave you nor forsake you.”
Ps 118:6
The Lord is with me; I will not be afraid. What can mere mortals do to me?
And of course Psalm 23.
