Then Moses went up with Aaron, Nadab and Abihu, and seventy of the elders of Israel, and they saw the God of Israel; and under His feet there appeared to be a pavement of sapphire, as clear as the sky itself.  Yet He did not stretch out His hand against the nobles of the sons of Israel; and they saw God, and they ate and drank.  (Exodus 24:9-11, NASB)
