Exodus 24:8-10

King James Version

⁸ And 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.

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