3 John 1:9-10

9I wrote unto the Assembly: but Diotrephes, who loveth to have the preeminence among them, receiveth us not. 10Wherefore, 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 Assembly.
