Although there is nothing said in the Book of Genesis in relation to sacrifices offered up by Enos, who was the son of Seth, nor by his descendants, Canaan, Mahalaleel, Jared, Enoch and Methuselah, all of whom held the High Priesthood, and were consequently prophets of the Lord, yet it is quite reasonable to suppose that they, being of the promised seed through whom the Messiah was to come, did offer up sacrifices as commemorative of that great promised event. Further, in relation to this subject, we are informed in the Book of Doctrine and Covenants [Section 107, par. 53-57, p. 389,] that "three years previous to the death of Adam, he called Seth, Enos, Cainan, Mahalaleel, Jared-Enoch and Methuselah [the persons mentioned above,] who were all High Priests, with the residue of his posterity who were righteous, into the valley of Adam-ondi-Ahman, and there bestowed upon them his last blessing. And the Lord appeared unto them, and they rose up and blessed Adam, and called him Michael, the Prince, the Archangel. And the Lord administered comfort unto Adam, and said unto him, I have set thee to be at the head--a multitude of nations shall come of thee, and thou art a prince over them for ever. And Adam stood up in the midst of the congregation, and notwithstanding he was bowed down with age, being full of the Holy Ghost, predicted whatsoever should befall his posterity unto the latest generation. These things were all written in the Book of Enoch, and are to be testified of in due time." Although, in the above, there is nothing directly said about the offering of sacrifices, yet, as this was a usual ceremony, and it belonged to the Priesthood and to the promised seed to offer sacrifices, it would be reasonable to suppose that Adam did then and there officiate in that rite; indeed, it was stated by the Prophet Joseph Smith, in our hearing, while standing on an elevated piece of ground or plateau near Adam-ondi-Ahman[A] (Davis Co., Missouri,), where there were a number of rocks piled together, that the valley before us was the valley of Adam-ondi-Ahman; or in other words, the valley where God talked with Adam, and where he gathered his righteous posterity, as recorded in the above revelation, and that this pile of stones was an altar built by him when he offered up sacrifices, as we understand, on that occasion. If Adam then offered up sacrifices in the presence of these prominent men, he being the President of these High Priests, he would officiate for them as well as for himself; while it is quite reasonable to believe that they assisted in the offerings made upon that altar.
