5. Again, Moses had the command of God, Numb. xi. 16: _Gather to me seventy men of the elders of Israel, whom thou knowest that they are the elders of the people, and governors over them, and bring them unto the tabernacle, &c._ And Moses, verse 24, did accordingly. And these were chosen to help Moses in bearing the burthen of the government, as appeareth, verse 17 of the same chapter. And as the twelve princes of the tribes were according to the number of Jacob’s children; so were the seventy elders according to the number of the persons that went down with Jacob into Egypt. In like manner our Saviour in his kingdom of Heaven, the church, out of the whole number of those that believed in him, ordained seventy persons, which peculiarly were called the seventy disciples, to whom he gave power to preach the Gospel and baptize. [Sidenote: The hierarchy of the church in our Saviour’s time, consisted in the twelve, and in the seventy.] 6. In our Saviour’s time therefore, the hierarchy of the church consisted, besides himself that was the head, of twelve apostles, who were equal amongst themselves, but ordained over others, as were the twelve heads of the tribes, and seventy disciples, who had every one of them power to baptize and teach, and help to govern the whole flock. [Sidenote: Why Christ ordained no priests for sacrifices, as Moses did.] 7. And whereas in the commonwealth instituted by Moses, there was not only a high-priest for the present, but also a succession and order of priests; it may be demanded, why our Saviour Christ did not ordain the like? To which may be answered, that the high-priesthood, forasmuch as concerneth the authority thereof, was in the person of Christ, as he was Christ, that is king. So also was it in Moses, Aaron having the ministerial part only. For notwithstanding that Aaron was the high-priest, yet the consecration of him belonged (Exod. xxix. 1) to Moses. All the utensils of sacrifice, and other holy things, were ordered by Moses; and in sum, the whole Levitical law was delivered by God by the hand of Moses, who was to Aaron a God, and Aaron to him a mouth. And for the ministerial part, there could no high-priest be ordained but himself; for seeing our Saviour was himself the sacrifice, who but himself could offer him up? And for the celebration of that sacrifice for ever after, our Saviour annexed the priesthood to those whom he had appointed to govern in the church.
