Exodus 24:1-2, 12

Then he said to Moses, “Come up to the LORD, you and Aaron, Nadab, and Abihu, and seventy of the elders of Israel, and worship from afar. Moses alone shall come near to the LORD, but the others shall not come near, and the people shall not come up with him.”

The LORD said to Moses, “Come up to me on the mountain and wait there, that I may give you the tablets of stone, with the law and the commandment, which I have written for their instruction.”
