Leviticus

And Moses went up unto God, and the Lord called unto him out of the mountain, saying, Thus shalt thou say to the house of Jacob, and tell the children of Israel;

And there I will meet with thee, and I will commune with thee from above the mercy seat, from between the two cherubims which are upon the ark of the testimony, of all things which I will give thee in commandment unto the children of Israel.

And when Moses was gone into the tabernacle of the congregation to speak with him, then he heard the voice of one speaking unto him from off the mercy seat that was upon the ark of testimony, from between the two cherubims: and he spake unto him.

Then a cloud covered the tent of the congregation, and the glory of the Lord filled the tabernacle.

And Moses was not able to enter into the tent of the congregation, because the cloud abode thereon, and the glory of the Lord filled the tabernacle.
