29a 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.
29b These things were all written in the Book of Enoch, and are to be testified of in due time.
30 It is the duty of the Twelve, also, to ordain and set in order all the other officers of the church, agreeably to the revelation which says:
31a To the church of Christ in the land of Zion, in addition to the church laws, respecting church business:
31b Verily, I say unto you, saith the Lord of hosts, There must needs be presiding elders, to preside over those who are of the office of an elder; and also priests, to preside over those who are of the office of a priest;
31c and also teachers to preside over those who are of the office of a teacher, in like manner; and also the deacons:
31d wherefore, from deacon to teacher, and from teacher to priest, and from priest to elder, severally as they are appointed, according to the covenants and commandments of the church;
31e then comes the high priesthood, which is the greatest of all; wherefore, it must needs be that one be appointed, of the high priesthood, to preside over the priesthood; and he shall be called president of the high priesthood of the church, or, in other words, the presiding high priest over the high priesthood of the church.
31f From the same comes the administering of ordinances and blessings upon the church, by the laying on of the hands.
32a Wherefore the office of a bishop is not equal unto it, for the office of a bishop is in administering all temporal things:
32b nevertheless, a bishop must be chosen from the high priesthood, unless he is a literal descendant of Aaron; for unless he is a literal descendant of Aaron he can not hold the keys of that priesthood.
