Exodus 21-24: Fire on the Mountain

Two things stand out in these chapters.  The first is that although the Ten Commandments should have been enough of a guideline for the Israelites to live their lives faultless before God, they were not enough.  So Moses is given further clarification of the law to pass on to them:  Laws for how they should treat their servants, laws about the response to violence, laws about animal control, laws about the responsibility of property, moral and ceremonial principles, justice for all, laws for the Sabbath and laws for their three feasts.  The Israelites must have understood them all, because they replied to Moses that they would obey all of these laws.  Whether the ensuing generations would follow these laws remained to be seen.

The second thing that stands out in these chapters is the mountain of God.  Moses has seen God before, at the burning bush, and still lived.  Now, God invites Moses to bring others up to the mountain,  Then Moses went up, also Aaron, Nadab, and Abihu, and seventy of the elders of Israel,  and they saw the God of Israel. And there was under His feet as it were a paved work of sapphire stone, and it was like the very heavens in its clarity. But on the nobles of the children of Israel He did not lay His hand. So they saw God, and they ate and drank.". - Exodus 24:9-11 NKJV

Did this small contingency of Israelites see the same thing that John saw in Revelation?  "And from the throne proceeded lightnings, thunderings, and voices. Seven lamps of fire were burning before the throne, which are the seven Spirits of God.  Before the throne there was a sea of glass, like crystal." - Revelations 4: 5-6 NKJV

 Is that the same mountain that Isaiah talks about?  "Many people shall come and say, “ Come, and let us go up to the mountain of the LORD, To the house of the God of Jacob; He will teach us His ways, And we shall walk in His paths.” For out of Zion shall go forth the law, And the word of the LORD from Jerusalem. - Isaiah 2:3 NKJV
 
On that mountain, the Alpha and Omega sits, on a throne surrounded by a shining sea.  His law goes forth from there and we're expected to eat and drink.
