Exodus 24:1-2, 12

Then the LORD said to Moses, “Come up to the LORD, you and Aaron, Nadab and Abihu, and seventy of the elders of Israel. You are to worship at a distance, but Moses alone is to approach the LORD; the others must not come near. And the people may not come up with him.”

The LORD said to Moses, “Come up to me on the mountain and stay here, and I will give you the tablets of stone with the law and commandments I have written for their instruction.”
