Moroni 3

 Moroni explains - 

"The manner which the disciples, who were called the elders of the church, ordained priests and teachers—

2 After they had prayed unto the Father in the name of Christ, they laid their hands upon them, and said:

3 In the name of Jesus Christ I ordain you to be a priest (or if he be a teacher, I ordain you to be a teacher) to preach repentance and remission of sins through Jesus Christ, by the endurance of faith on his name to the end. Amen."  (Moroni 3:1–3)

In a sense, an important instruction in the handbook of instructions.
