Exodus 24:9-11

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

10and they saw the 1God 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.

11And on the nobles of the children of Israel he laid not his hand: they saw 2God, and ate and drank.
