Proverbs 4:14-16, 18-19

Do not enter the path of the wicked, and do not walk in the way of the evil. Avoid it; do not go on it; turn away from it and pass on. For they cannot sleep unless they have done wrong; they are robbed of sleep unless they have made someone stumble.

But the path of the righteous is like the light of dawn, which shines brighter and brighter until full day. The way of the wicked is like deep darkness; they do not know over what they stumble.
