Exodus 24:1-3

He said to Moses, “Climb the mountain to GOD, you and Aaron, Nadab, Abihu, and seventy of the elders of Israel. They will worship from a distance; only Moses will approach GOD. The rest are not to come close. And the people are not to climb the mountain at all.” So Moses went to the people and told them everything GOD had said—all the rules and regulations. They all answered in unison: “Everything GOD said, we’ll do.”
