1 Corinthians 6:4-6

King James Version

⁴ If then ye have judgments of things pertaining to this life, set them to judge who are least esteemed in the church.

⁵ I speak to your shame. Is it so, that there is not a wise man among you? no, not one that shall be able to judge between his brethren?

⁶ But brother goeth to law with brother, and that before the unbelievers.
