Discussing the Endowment:

"Bro[ther] Joseph [Smith] turned to me [Brigham Young] and said: “Brother Brigham this is not arranged right, but we have done the best we could under the circumstances in which we are placed, and I wish you to take this mat[t]er in hand and organize and systematize all these ceremonies with the signs, tokens, penalties and key words.” I did so and each time I got something more; so that when we went through the Temple at Nauvoo, I understood and knew how to place them there. We had our ceremonies pretty correct."
