2Moses alone shall approach the LORD, but the others must not come near. And the people may not go up with him.”
3When Moses came and told the people all the words and ordinances of the LORD, they all responded with one voice: “All the words that the LORD has spoken, we will do.”
4And Moses wrote down all the words of the LORD. Early the next morning he got up and built an altar at the base of the mountain, along with twelve pillars for the twelve tribes of Israel.
