Exodus 24:1-3

1Then He said to Moses, “1Come up to the Lord, you and Aaron, 2Nadab and Abihu, and 3seventy of the elders of Israel, and you shall worship at a distance. 2Moses alone, however, shall approach the Lord, but they shall not approach, nor shall the people come up with him.”

3Then Moses came and reported to the people all the words of the Lord and all the 4ordinances; and all the people answered with one voice and said, “5All the words which the Lord has spoken we will do!”
