Psalms 119:30-36

I have chosen the way of faithfulness; I have set my heart on your laws. I hold fast to your statutes, LORD; do not let me be put to shame. I run in the path of your commands, for you have broadened my understanding. Teach me, LORD, the way of your decrees, that I may follow it to the end. Give me understanding, so that I may keep your law and obey it with all my heart. Direct me in the path of your commands, for there I find delight. Turn my heart toward your statutes and not toward selfish gain.
