Proverbs 28:16, 26

A leader who is a great oppressor lacks understanding and common sense [and his wickedness shortens his days], But he who hates unjust gain will [be blessed and] prolong his days.

He who trusts confidently in his own heart is a [dull, thickheaded] fool, But he who walks in [skillful and godly] wisdom will be rescued. [James 1:5]
