Exodus 40:35

35And Moses was not able to enter the tent of meeting because the cloud settled on it, and the glory of the Lord filled the tabernacle.

Leviticus 16:2-13

2and the Lord said to Moses, “Tell Aaron your brother not to acome at any time into the Holy Place inside the veil, before the mercy seat that is on the ark, so that he may not die. For bI will appear in the cloud over the mercy seat. 3But in this way Aaron shall come into the Holy Place: cwith a bull from the herd for a sin offering and da ram for a burnt offering. 4He shall put on ethe holy linen coat and shall have the linen undergarment on his body, and he shall tie the linen sash around his waist, and wear the linen turban; these are the holy garments. fHe shall bathe his body in water and then put them on. 5And he shall take from gthe congregation of the people of Israel two male goats for a sin offering, and one ram for a burnt offering.

6Aaron shall hoffer the bull as a sin offering for himself and shall imake atonement for himself and for his house. 7Then he shall take the two goats and set them before the Lord at the entrance of the tent of meeting. 8And Aaron shall cast lots over the two goats, one lot for the Lord and the other lot for jAzazel.
The meaning of  Azazel is uncertain; possibly the name of a place or a demon, traditionally a scapegoat; also verses 10, 26
9And Aaron shall present the goat on which the lot fell for the Lord and use it as a sin offering, 10but the goat on which the lot fell for lAzazel shall be presented alive before the Lord to make atonement over it, that it may be sent away into the wilderness to mAzazel.

11Aaron shall present nthe bull as a sin offering for himself, and shall make atonement for himself and for his house. He shall kill the bull as a sin offering for himself. 12And he shall take oa censer full of coals of fire from the altar before the Lord, and two handfuls of sweet incense beaten small, and he shall bring it inside the veil 13 pand put the incense on the fire before the Lord, that the cloud of the incense may cover qthe mercy seat that is over the testimony, so that he does not die.

Deuteronomy 4:24

24For rthe Lord your God is a consuming fire, sa jealous God.
