55. We can tell how supremely holy they were from the fact that Jehovah himself - the Lord, that is - came down upon Mount Sinai in fire, with angels, and proclaimed them from there with his own voice, and that the people spent three days preparing themselves for seeing and hearing all this. The mountain was also fenced off so that no one would approach it and die. Not even priests or elders were allowed near; Moses alone was allowed. The laws were written on two stone tablets by the finger of God. When Moses brought the tablets down from the mountain the second time, his face shone. Later they were placed in an ark, which was set in the very heart of the tabernacle and had a mercy seat on it, with angel guardians made of gold above that. There was nothing holier in their church, and it was called "the most holy place." Outside the veil that surrounded it they brought together things that represented holy elements of heaven and the church - the lampstand with its seven golden lamps, the golden altar of incense, and the gilded table for the showbread, all surrounded by curtains of fine linen and purple and scarlet thread. The sole reason for the holiness of this whole tabernacle was the law that was in the ark.
[2] Because of the holiness of the tabernacle, which resulted from the presence of the law in the ark, the whole Israelite population camped around it, in a set arrangement tribe by tribe, and traveled behind it in a set sequence. There was also a cloud above it in the daytime then, and fire above it at night. Because of the holiness of the law and the Lord's presence in it, it was upon the mercy seat between the angel guardians that the Lord spoke to Moses, and the ark was called "Jehovah" there. In fact Aaron was not allowed to go behind the veil without sacrifices and incense.
Because the law was the essential holiness of the church, David brought the ark into Zion, and it was later placed at the center of the Jerusalem temple where [Solomon] had made an inner sanctuary for it.
[3] Because of the Lord's presence in and around the law, miracles were performed by means of the ark in which the law lay. For example, the waters of the Jordan were cut off, and as long as the ark rested in its midst, the people crossed over on dry ground. The walls of Jericho fell because the ark was carried around them. Dagon, the god of the Philistines, fell before the ark and later lay on the threshold of the shrine with its head broken off. Tens of thousands of the people of Beth-shemesh were struck down because of the ark, and so on. All these things happened simply because of the Lord's presence in his "Ten Words, " which are the Ten Commandments.
