The Lord said to Moses, “Come up to me on this mountain. Bring along Aaron, as well as his two sons Nadab and Abihu, and seventy of Israel’s leaders. They must worship me at a distance, but you are to come near. Don’t let anyone else come up.” . . .Moses and Aaron, together with Nadab and Abihu and the seventy leaders, went up the mountain and saw the God of Israel. Under his feet was something that looked like a pavement made out of sapphire and it was as bright as the sky.
Even though these leaders of Israel saw God, he did not punish them. So they ate and drank.
