2 Samuel 22:30-31 – For by You I can run against a troop; by my God I can leap over a wall. As for God, His way is perfect; the word of the Lord is proven.
Isaiah 55:10-11 – As the rain and snow come down from heaven, and do not return to it without watering the earth . . . so is my word that goes out from my mouth: It will not return to me empty, but will accomplish what I desire.
