Proverbs 4:19-23

The way of the wicked is as darkness: they know not at what they stumble.

My son, attend to my words; incline thine ear unto my sayings.

Let them not depart from thine eyes; keep them in the midst of thine heart.

For they are life unto those that find them, and health to all their flesh.

Keep thy heart with all diligence; for out of it are the issues of life.
