1 Wakorintho 5 : 11 1st Corinthians chapter 5 verse 11

Lakini, mambo yalivyo, naliwaandikia kwamba msichangamane na mtu aitwaye ndugu, akiwa ni mzinzi au mwenye kutamani au mwenye kuabudu sanamu au mtukanaji au mlevi au mnyang'anyi; mtu wa namna hii msikubali hata kula naye.
soma Mlango wa 5

But as it is, I wrote to you not to associate with anyone who is called a brother who is a sexual sinner, or covetous, or an idolater, or a slanderer, or a drunkard, or an extortioner. Don't even eat with such a person.
