Exodus 24:9-14

9Then went up Moses, and Aaron, Nadab, and Abihu, and seventy of the elders of Israel: 10and they saw the God of Israel; and there was under his feet as it were a paved work of sapphire stone, and as it were the very heaven for clearness. 11And upon the nobles of the children of Israel he laid not his hand: and they beheld God, and did eat and drink.

12And Jehovah said unto Moses, Come up to me into the mount, and be there: and I will give thee the tables of stone, and the law and the commandment, which I have written, that thou mayest teach them. 13And Moses rose up, and Joshua his minister: and Moses went up into the mount of God. 14And he said unto the elders, Tarry ye here for us, until we come again unto you: and, behold, Aaron and Hur are with you: whosoever hath a cause, let him come near unto them.
