18But the ways of the righteous shine like light; they go on and shine, until the day be fully come.
19But the ways of the ungodly are dark; they know not how they stumble.
20My son, attend to my speech; and apply your ear to my words:
21that your fountains may not fail you; keep them in your heart.
Proverbs 4
