Exod 24:9-11

On the Mountain with God 9Then Moses and Aaron, Nadab, and Abihu, and seventy of the elders of Israel went up,10and they saw the God of Israel. Under his feet there was something like a pavement of sapphire stone, like the very heaven for clearness.11God did not lay his hand on the chief men of the people of Israel; also they beheld God, and they ate and drank.
