'Welcome' in the Bible

So we ought to support such people [welcoming them as guests and providing for them], so that we may be fellow workers for the truth [that is, for the gospel message of salvation].

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.
