Thou wilt keep him in perfect peace, whose mind is stayed on thee: because he trusteth in thee. Isaiah 26:3 (KJV)
I will both lay me down in peace, and sleep:
for thou, Lord,
only makest me dwell in safety.
But thou, O Lord, art a shield for me; my glory, and the lifter up of mine head. Psalm 3:3 (KJV)
I will love thee, O Lord, my strength.
The Lord is my rock, and my fortress, and my deliverer; my God,
my strength, in whom I will trust;
my buckler, and the horn of my salvation, and my high tower.
I will call upon the Lord,
who is worthy to be praised:
so shall I be saved from mine enemies.
Psalm 18:1-3 (KJV)
