Isaiah 26:3,4
Thou wilt keep him in perfect peace, whose mind is
stayed on thee: because he trusteth in thee. Trust
ye in the LORD for ever: for in the LORD JEHOVAH is
everlasting strength:
Philippians 4:6,7
Be careful for nothing; but in every thing by
prayer and supplication with thanksgiving let your
requests be made known unto God. And the peace of
God, which passeth all understanding, shall keep
your hearts and minds through Christ Jesus.
