191 Exactly two months after the Israelites left Egypt, they arrived in the wilderness of Sinai. 2 After breaking camp at Rephidim, they came to the wilderness of Sinai and set up camp there at the base of Mount Sinai. 3 Then Moses climbed the mountain to appear before God. The Lord called to him from the mountain and said, "Give these instructions to the family of Jacob; announce it to the descendants of Israel: 4 'You have seen what I did to the Egyptians. You know how I carried you on eagles' wings and brought you to myself. 5 Now if you will obey me and keep my covenant, you will be my own special treasure from among all the peoples on earth; for all the earth belongs to me. 6 And you will be my kingdom of priests, my holy nation.' This is the message you must give to the people of Israel."

Commentary on Exodus 19:1-8
(Read Exodus 19:1-8)
Moses was called up the mountain, and was employed as the messenger of this covenant. The Maker and first Mover of the covenant, is God himself. This blessed charter was granted out of God's own free grace. The covenant here mentioned was the national covenant, by which the Israelites were a people under the government of Jehovah. It was a type of the new covenant made with true believers in Christ Jesus; but, like other types, it was only a shadow of good things to come. As a nation they broke this covenant; therefore the Lord declared that he would make a new covenant with Israel, writing his law, not upon tables of stone, but in their hearts, Jeremiah 31:33; Hebrews 8:7-10. The covenant spoken of in these places as ready to vanish away, is the national covenant with Israel, which they forfeited by their sins. Unless we carefully attend to this, we shall fall into mistakes while reading the Old Testament. We must not suppose that the nation of the Jews were under the covenant of works, which knows nothing of repentance, faith in a Mediator, forgiveness of sins, or grace; nor yet that the whole nation of Israel bore the character, and possessed the privileges of true believers, as being actually sharers in the covenant of grace. They were all under a dispensation of mercy; they had outward privileges and advantages for salvation; but, like professing Christians, most rested therein, and went no further. Israel consented to the conditions. They answered as one man, All that the Lord hath spoken we will do. Oh that there had been such a heart in them! Moses, as a mediator, returned the words of the people to God. Thus Christ, the Mediator, as a Prophet, reveals God's will to us, his precepts and promises; and then, as a Priest, offers up to God our spiritual sacrifices, not only of prayer and praise, but of devout affections, and pious resolutions, the work of his own Spirit in us.
