ACV(i) 3 And Moses came and told the people all the words of LORD, and all the ordinances. And all the people answered with one voice, and said, All the words which LORD has spoken will we do. 4 And Moses wrote all the words of LORD, and rose up early in the morning, and built an altar below the mount, and twelve pillars, according to the twelve tribes of Israel.
