1 Corinthians 5:11-13

Young's Literal Translation

¹¹ and now, I did write to you not to keep company with [him], if any one, being named a brother, may be a whoremonger, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner -- with such a one not even to eat together;

¹² for what have I also those without to judge? those within do ye not judge?

¹³ and those without God doth judge; and put ye away the evil from among yourselves.
