The opening up of Your Word gives light, and understanding.

Your Laws are wonderful, and so I obey them. The opening up of Your Word gives light. It gives understanding to the child-like. I opened my mouth wide, breathing with desire for Your Law. Turn to me and show me loving-favor, as You always do to those who love Your name. Set my steps in Your Word. Do not let sin rule over me. Set me free from the power of man, and I will obey Your Law. Make Your face shine upon Your servant and teach me Your Law. Tears flow from my eyes because of those who do not keep Your Law.
Psalm 119:129-136 - NLV
