Irenaeus: Demonstration of the Apostolic Preaching

26. And in the wilderness Moses received the Law from God, the Ten Words on tables of stone, written with the finger of God (now the finger of God is that which is stretched forth from the Father in the Holy Spirit); ^[1] and the commandments and ordinances which he delivered to the children of Israel to observe. And the tabernacle of witness he constructed by the command of God, the visible form on earth of those things which are spiritual and invisible in the heavens, and a figure of the form of the Church, and a prophecy of things to come: in which also were the vessels and the altars of sacrifice and the ark in which he placed the tables (of the Law). And he appointed as priests Aaron and his sons, assigning the priesthood to all their tribe: and they were of the seed of Levi. Moreover this whole tribe he summoned by the word of God to accomplish the work of service in the temple of God, and gave them the Levitical law, (to shew) what and what manner of men they ought to be who are continually employed in performing the service of the temple of God.
