Exodus 24:9-18

Then went up Moses, and Aaron, Nadab, and Abihu, and seventy of the elders of Israel: and they saw the God of Israel: and there was under his feet as it were a paved work of a sapphire stone, and as it were the body of heaven in his clearness. And upon the nobles of the children of Israel he laid not his hand: also they saw God, and did eat and drink. And the LORD said unto Moses, Come up to me into the mount, and be there: and I will give thee tables of stone, and a law, and commandments which I have written; that thou mayest teach them. And Moses rose up, and his minister Joshua: and Moses went up into the mount of God. And he said unto the elders, Tarry ye here for us, until we come again unto you: and, behold, Aaron and Hur are with you: if any man have any matters to do, let him come unto them. And Moses went up into the mount, and a cloud covered the mount. And the glory of the LORD abode upon mount Sinai, and the cloud covered it six days: and the seventh day he called unto Moses out of the midst of the cloud. And the sight of the glory of the LORD was like devouring fire on the top of the mount in the eyes of the children of Israel. And Moses went into the midst of the cloud, and gat him up into the mount: and Moses was in the mount forty days and forty nights.
