1 Corinthians 6:4-6

Young's Literal Translation

⁴ of the things of life, indeed, then, if ye may have judgment, those despised in the assembly -- these cause ye to sit;

⁵ unto your shame I speak: so there is not among you one wise man, not even one, who shall be able to discern in the midst of his brethren!

⁶ but brother with brother doth go to be judged, and this before unbelievers!
