Proverbs 8:8 (NKJV) — 8 All the words of my mouth are with righteousness; Nothing crooked or perverse is in them.
Righteousness contrasted with crookedness and perversity. The word translated “crooked” has to do with self-will, stubbornness, and rebellion. Perversity involves twisting or warping what is right and good. In contrast, righteousness submits to the will of God and walks in His ways. Those who speak with a crooked or perverse mouth disclose that they lack wisdom.
