'Slanderer' in the Bible

"'You shall not go up and down as a slanderer among your people. "'You shall not endanger the life of your neighbor. I am Yahweh.

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.
