2 Samuel 22:26-31 ESV

“With the merciful you show yourself merciful; with the blameless man you show yourself blameless; with the purified you deal purely, and with the crooked you make yourself seem tortuous. You save a humble people, but your eyes are on the haughty to bring them down. For you are my lamp, O LORD, and my God lightens my darkness. For by you I can run against a troop, and by my God I can leap over a wall. This God—his way is perfect; the word of the LORD proves true; he is a shield for all those who take refuge in him.
