And he declared unto you his covenant,.... So the law was called, because it contained, on the part of God, things which he would have done or avoided, to which were annexed promises of long life and happiness in the land he gave them; and they, on their part, agreed to hearken to it, and obey it, Exodus 24:3,

which he commanded you to perform, even ten commandments; which see at large in Exodus 20:1, and in this book afterwards repeated, Deuteronomy 5:6,

and he wrote them upon two tables of stone; to denote the durableness of them; the Targum of Jonathan says on tables of sapphire; but it is most likely that they were written on tables of marble, since there were great quantities of it in Mount Sinai; See Gill on Exodus 31:18.

The Israelites, therefore, could not see a form of God, but could only hear the voice of His words, when the Lord proclaimed His covenant to them, and gave utterance to the ten words, which He afterwards gave to Moses written upon two tables of stone (Exodus 20:1-14 [17], and Exodus 31:18, compared with Exodus 24:12). On the "tables of stone," see at Exodus 34:1.

And he declared unto you his covenant, which he commanded you to {k} perform, even ten commandments; and he wrote them upon two tables of stone.

(k) God joins this condition to his covenant.

4:1-23 The power and love of God to Israel are here made the ground and reason of a number of cautions and serious warnings; and although there is much reference to their national covenant, yet all may be applied to those who live under the gospel. What are laws made for but to be observed and obeyed? Our obedience as individuals cannot merit salvation; but it is the only evidence that we are partakers of the gift of God, which is eternal life through Jesus Christ, Considering how many temptations we are compassed with, and what corrupt desires we have in our bosoms, we have great need to keep our hearts with all diligence. Those cannot walk aright, who walk carelessly. Moses charges particularly to take heed of the sin of idolatry. He shows how weak the temptation would be to those who thought aright; for these pretended gods, the sun, moon, and stars, were only blessings which the Lord their God had imparted to all nations. It is absurd to worship them; shall we serve those that were made to serve us? Take heed lest ye forget the covenant of the Lord your God. We must take heed lest at any time we forget our religion. Care, caution, and watchfulness, are helps against a bad memory.
