2 Samuel 22:27-31

With the pure thou wilt show thyself pure; And with the perverse thou wilt show thyself froward.

And the afflicted people thou wilt save; But thine eyes are upon the haughty, that thou mayest bring them down.

For thou art my lamp, O Jehovah; And Jehovah will lighten my darkness.

For by thee I run upon a troop; By my God do I leap over a wall.

As for God, his way is perfect: The word of Jehovah is tried; He is a shield unto all them that take refuge in him.
