 My son, attend to my words, incline thine ear unto my sayings. Let them not depart from thine eyes, keeping them in the midst of thine heart, for they are life unto those that find them and health to all their flesh. Proverbs 16, verse 15 and Proverbs 19, verse 23 refer to life as our joy or our peace or our satisfaction. It's that thing that brings fulfillment. In the light of the king's countenance is life.
