To understand the spiritual elements you have to view them from that perspective.
The heavenly vision starts in Ex 24, where God tells Moses to 'come up'
But to Moses the LORD said, “Come up to the LORD, you and Aaron, Nadab and Abihu, and seventy of the elders of Israel, and worship from a distance. Moses alone may come near the LORD, but the others must not come near, nor may the people go up with him.”
Moses and Aaron, Nadab and Abihu, and the seventy elders of Israel went up, and they saw the God of Israel. Under his feet there was something like a pavement made of sapphire, clear like the sky itself. But he did not lay a hand on the leaders of the Israelites, so they saw God, and they ate and they drank.
The LORD said to Moses, “Come up to me on the mountain and remain there, and I will give you the stone tablets with the law and the commandments that I have written, so that you may teach them.” So Moses set out with Joshua his attendant, and Moses went up the mountain of God.
Moses went into the cloud when he went up the mountain, and Moses was on the mountain 40 days and 40 nights.
There is a significant misunderstanding here, but I'll leave it for another day. Moses was shown heavenly things-- God didn't come down, -Moses went up. This is significant in that Moses, Aaron, Nadab, Abihu, the seventy elders and Joshua were shown spiritual concepts, not physical. This is clear from the description of what scripture provides (something like....)
If you don't understand the spiritual significance of this being a spiritual scene-- you'll miss it. Just like Moses did.
You'll mistake and misunderstand spiritual concepts and you'll become a literalist- and you'll make a fool of yourself.
On the seventh day He called to Moses from within the cloud. Moses went into the cloud when he went up the mountain, and Moses was on the mountain 40 days and 40 nights.
The LORD spoke to Moses, “Tell the Israelites to take an offering for me; from every person motivated by a willing heart you are to receive my offering. This is the offering you are to accept from them: gold, silver, bronze, blue, purple, scarlet, fine linen, goats’ hair, ram skins dyed red, fine leather, acacia wood, oil for the light, spices for the anointing oil and for fragrant incense, onyx stones, and other gems to be set in the ephod and in the breastpiece. Let them make for me a sanctuary, so that I may live among them. According to all that I am showing you —the pattern of the tabernacle and the pattern of all its furnishings—you must make it exactly so.
To understand the oil, first you have to consider the Lamps and the Lampstand....
