And he gave unto Moses, when he had made an end of communing with him upon Mount Sinai, two tables of testimony, tables of stone, written with the finger of God.
Moses, after forty days in the mount, comes down And he was there with the Lord forty days and forty nights; he did neither eat bread, nor drink water. And he wrote upon the tables the words of the covenant, the Ten Commandments.
1 Kings 8:9,21
9 There was nothing in the ark except the two tablets of stone which Moses put there at Horeb, where the Lord made a covenant with the sons of Israel, when they came out of the land of Egypt.”
21 “And there I have set a place for the ark, in which is the covenant of the Lord, which He made with our fathers when He brought them from the land of Egypt.”
“When I went up to the mountain to receive the tablets of stone, the tablets of the covenant which the Lord had made with you, then I remained on the mountain forty days and nights; I neither ate bread nor drank water.
“The Lord our God made a covenant with us at Horeb. The Lord did not make this covenant with our fathers, but with us, with all those of us alive here today.” (Ten Commandments are given in Deuteronomy 5)
The tables are part of the abolished first covenant: Heb 8:13 When He said, “A new covenant,” He has made the first obsolete. But whatever is becoming obsolete and growing old is ready to disappear. “Now even the first covenant had … the TABLES OF THE COVENANT.”
“So He declared to you His covenant which He commanded you to perform, that is, the Ten Commandments; and He wrote them on two tablets of stone.
“The Law and Gospel are two keys. The law is the key that shutteth up all men under condemnation, and the gospel is the key which opens the door and lets them out.”—William Tyndale.
