'Excommunicate' in the Bible

Blessed [morally courageous and spiritually alive with life-joy in God’s goodness] are you when people hate you, and exclude you [from their fellowship], and insult you, and scorn your name as evil because of [your association with] the Son of Man.

For this reason, if I come, I will call attention to what he is doing, unjustly accusing us with wicked words and unjustified charges. And not satisfied with this, he refuses to receive the [missionary] brothers himself, and also forbids those who want to [welcome them] and puts them out of the church.
