“You (God) will keep him in perfect peace (in the Hebrew Scriptures it literally reads “peace, peace” – – a double portion of peace)! whose mind is stayed on You, because he trusts in You. Trust in the LORD forever, for in YAH (abbreviation for ‘Jehovah’) the LORD is everlasting strength” (Isaiah 26:3, 4)
“‘There is no peace,’ says the LORD, ‘for the wicked (the one/s morally wrong)‘” (Isaiah 48:22; 57:21)

“Peace I (The Lord Jesus Christ, the Messiah) leave with you, My peace I give to you; not as the world gives do I give to you. Let not your heart (mind, emotions and will) be troubled (or agitated, like boiling water), neither let it be afraid” (John 14:27)
“These things I (The Lord Jesus Christ, the Messiah) have spoken to you, that in Me you may have peace. In the world you will have tribulation; but be of good cheer, I have overcome the world” (John 16:33)
“Be anxious for nothing, but in everything be prayer and supplication, with thanksgiving, let your requests be made known to God; and the peace of God, which surpasses all understanding, will guard your hearts and minds through Christ Jesus” (Philippians 4:6, 7)
“For when they (not God) say, ‘Peace and safety!’ then sudden destruction comes upon them, as labor pains upon a pregnant woman. And they shall not escape” (I Thessalonians 5:3)
Someone has once defined peace as “the heart at rest with God!”
