Psalm 18:24-28

So the LORD has rewarded me according to my righteousness, according to the cleanness of my hands in his sight. With the merciful you show yourself merciful; with the blameless man you show yourself blameless; with the purified you show yourself pure; and with the crooked you make yourself seem tortuous. For you save a humble people, but the haughty eyes you bring down. For it is you who light my lamp; the LORD my God lightens my darkness.
