I say unto you, be one

D&C 38: 24-27 And let every man esteem his brother as himself, and practice virtue and holiness before me. And again I say unto you, let every man esteem his brother as himself. For what man among you having twelve sons, and is no respecter of them, and they serve him obediently, and he saith unto the one: Be thou clothed in robes and sit thou here; and to the other: Be thou clothed in rags and sit thou there—and looketh upon his sons and saith I am just? Behold, this I have given unto you as a parable, and it is even as I am. I say unto you, be one; and if ye are not one ye are not mine.
