Exodus 24:8-10

Darby Translation

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

⁹ And Moses and Aaron, Nadab and Abihu, and seventy of the elders of Israel went up;

¹⁰ and they saw the God of Israel; and there was under his feet as it were work of transparent sapphire, and as it were the form of heaven for clearness.
