Exodus 24:9

7And he took the book of the covenant, and read in the audience of the people: and they said, All that the LORD hath said will we do, and be obedient.

8And Moses took the blood, and sprinkled it on the people, and said, Behold the blood of the covenant, which the LORD hath made with you concerning all these words.

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 a sapphire stone, and as it were the body of heaven in his clearness.

11And upon the nobles of the children of Israel he laid not his hand: also they saw God, and did eat and drink.
