Exodus is not specific, but it certainly indicates it. Read through the next 5 chapters. It is fascinating and describes the Ark or the sanctuary of the Lord and its construction and materials, which some of the Reformed have violently objected to when constructed in a Catholic church.
Ridiculous. The Ark was so holy that no one, not even the Levite priests looked upon it. Whenever it went out among the people it was covered in heavy cloth and shielded from view.
It was uncovered in the inner sanctum and every High Priest who went into the inner sanctum, had to be pure before the Lord or he was struck dead. He used to have a rope attached to him so the priests could pull him out if this happened.
