John 14:27 ESV
Peace I leave with you; my peace I give to you. Not as the world gives do I give to you. Let not your hearts be troubled, neither let them be afraid.
Philippians 4:5b-7 ESV
The Lord is at hand; ⁶ do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. ⁷ And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus.
