"Then Moses came and recounted to the people all the words of the Lord and all the ordinances; and all the people answered with one voice and said, 'All the words which the Lord has spoken we will do!'" (Ex 24:3). "Moses wrote down all the words of the Lord" (:4). "Then he took the book of the covenant and read it in the hearing of the people; and they said, 'All that the Lord has spoken we will do, and we will be obedient!'" (:7). "Now the Lord said to Moses, 'Come up to Me on the mountain and remain there, and I will give you the stone tablets with the law and the commandment which I have written for their instruction'" (:12). Moses wrote the first five books of the Bible which are referred to as the Old Covenant. When God "had finished speaking with him upon Mount Sinai, He gave Moses the two tablets of the testimony, tablets of stone, written by the finger of God" (Ex 31:18). "The tablets were God's work, and the writing was God's writing engraved on the tablets" (32:16).
"On the seventh day He called to Moses from the midst of the cloud. And to the eyes of the sons of Israel the appearance of the glory of the Lord was like a consuming fire on the mountain top" (Ex 24:17-18). "Moses was on the mountain forty days and forty nights" (:18). But there was a problem in the camp and the Israelites had sinned. Moses then interceded for them and God modified what he was going to do. Moses said, "Remember Abraham, Isaac, and Israel, Your servants to whom You swore by Yourself, and said to them, 'I will multiply your descendants as the start of the heavens, and all this land of which I have spoken I will give to your descendants, and they shall inherit it forever'" (Ex 32:13).
