Psalms 17:3-5

For in a visitation of the night you inspected my heart and refined my soul in fire until nothing vile was found in me. I will not sin with my words. Following your word has kept me from wrong. Your ways have molded my footsteps, keeping me from going down the paths of the violent. My steps follow in the tracks of your chariot wheels, always staying in their path, never straying from your way.
