Exodus 24:1-4

1And he said to Moses, Come up to the LORD, thou, and Aaron, Nadab, and Abihu, and seventy of the elders of Israel; and worship ye afar off.

2And Moses alone shall come near the LORD: but they shall not come near; neither shall the people go up with him.

3And Moses came and told the people all the words of the LORD, and all the judgments: and all the people answered with one voice, and said, All the words which the LORD hath said will we do.

4And Moses wrote all the words of the LORD, and rose early in the morning, and built an altar under the hill, and twelve pillars, according to the twelve tribes of Israel.
