Exodus 24:1-4

1But to Moses the Lord said, “Come up to the Lord, you and Aaron, Nadab and Abihu, and seventy of the elders of Israel, and worship from a distance.

2Moses alone may come near the Lord, but the others must not come near, nor may the people go up with him.”

3Moses came and told the people all the Lord’s words and all the decisions. All the people answered together, “We are willing to do all the words that the Lord has said,”

4and Moses wrote down all the words of the Lord. Early in the morning he built an altar at the foot of the mountain and arranged twelve standing stones – according to the twelve tribes of Israel.
