Exodus 24:8

5 And he sent young men of the children of Israel, who offered burnt-offerings, and sacrificed peace-offerings of oxen unto Jehovah.

6 And Moses took half of the blood, and put it in basins; and half of the blood he sprinkled on the altar.

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

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

9 Then went up Moses, and Aaron, Nadab, and Abihu, and seventy of the elders of Israel.

10 And 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.

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