'Us' in the Bible

So it is right for us to take in such men as guests, so that we may take our part in the work of the true faith.

I wrote unto the church: but Diotrephes, who loveth to have the preeminence among them, receiveth us not.

Wherefore, if I come, I will remember his deeds which he doeth, prating against us with malicious words: and not content therewith, neither doth he himself receive the brethren, and forbiddeth them that would, and casteth them out of the church.
