Thou wilt keep him in perfect peace, whose mind is stayed on Thee.

The darkness is no darkness with Thee, 
but the night is as clear as the day: 
the darkness and light to Thee are both alike, 
God is light, and in Him is no darkness at all; 
O let my soul live, and it shall praise Thee, praise Thee, 
and it shall praise Thee, let my soul live and it shall praise Thee.

Thou wilt keep him in perfect peace, whose mind is stayed on Thee.

Isaiah 26:3, Psalm 139:11, Psalm 119:175
