Exodus 24:8-10

Living Bible

⁸ Then Moses threw the blood from the basins toward the people and said, “This blood confirms and seals the covenant the Lord has made with you in giving you these laws.”

⁹ Then Moses, Aaron, Nadab, Abihu, and seventy of the elders of Israel went up into the mountain. ¹⁰ And they saw the God of Israel; under his feet there seemed to be a pavement of brilliant sapphire stones, as clear as the heavens.
