D&C 88

 As the Lord introduces the "school of the prophets" which I believe developed more into priesthood meetings,  He spoke of the type of relationship these brethren should have teaching - 

"...when any shall come in after him, let the teacher arise, and, with uplifted hands to heaven, yea, even directly, salute his brother or brethren with these words:

133 Art thou a brother or brethren? I salute you in the name of the Lord Jesus Christ, in token or remembrance of the everlasting covenant, in which covenant I receive you to fellowship, in a determination that is fixed, immovable, and unchangeable, to be your friend and brother through the grace of God in the bonds of love, to walk in all the commandments of God blameless, in thanksgiving, forever and ever. Amen."  (Doctrine and Covenants 88:132–133)

And at the same time - 

"...he that cometh in and is faithful before me, and is a brother, or if they be brethren, they shall salute the president or teacher with uplifted hands to heaven, with this same prayer and covenant, or by saying Amen, in token of the same."  (Doctrine and Covenants 88:135)

I believe these words were not intended to be word for word but more of type of communication, for the Lord explained -

"...verily, I say unto you, this is an ensample unto you for a salutation to one another in the house of God, in the school of the prophets."  (Doctrine and Covenants 88:136)
