That first plan contained directions for worship, and a specially designed place of worship.
A large outer tent was set up. The lampstand, the table, and "the bread of presence" were placed in it. This was called "the Holy Place."
Then a curtain was stretched, and behind it a smaller, inside tent set up. This was called "the Holy of Holies."
In it were placed the gold incense altar and the gold-covered ark of the covenant containing the gold urn of manna, Aaron's rod that budded, the covenant tablets,
and the angel-wing-shadowed mercy seat. But we don't have time to comment on these now.
After this was set up, the priests went about their duties in the large tent.
Only the high priest entered the smaller, inside tent, and then only once a year, offering a blood sacrifice for his own sins and the people's accumulated sins.
This was the Holy Spirit's way of showing with a visible parable that as long as the large tent stands, people can't just walk in on God.
Under this system, the gifts and sacrifices can't really get to the heart of the matter, can't assuage the conscience of the people,
but are limited to matters of ritual and behavior. It's essentially a temporary arrangement until a complete overhaul could be made.
