I have been writing on God’s unconditional covenants with Israel. And we have indicated that the main covenant is the Abrahamic covenant. But there are three other tributary covenants: The Palestinian covenant, the Davidic covenant, and the New covenant. These three covenants, I think, sort of pull apart and explain in greater detail three aspect of the Abrahamic covenant. The Palestinian covenant explains in more detail the land aspect, the Davidic covenant explains the seed aspect, and the New covenant explains the blessing aspect.
The Palestinian Covenant
As Israel is ready to enter the land of promise (Deut. 28-30), they are faced by their enemies who will resist them. They have the promise from God that the land is theirs (Gen. 12:7), yet entering seems quite impossible. Also, many may have doubted that the Abrahamic covenant is still valid. The Palestinian covenant (or some have called it a Land covenant; the Bible does not give it a certain name), given to them by Moses (in Deuteronomy 30:1-10), supports the original promise and gives them confidence to enter.
“So it shall be when all of these things have come upon you, the blessing and the curse which I have set before you, and you call them to mind in all nations where the Lord your God has banished you, 2 and you return to the Lord your God and obey Him with all your heart and soul according to all that I command you today, you and your sons, 3 then the Lord your God will restore you from captivity, and have compassion on you, and will gather you again from all the peoples where the Lord your God has scattered you. 4 If your outcasts are at the ends of the earth, from there the Lord your God will gather you, and from there He will bring you back. 5 And the Lord your God will bring you into the land which your fathers possessed, and you shall possess it; and He will prosper you and multiply you more than your fathers. 6 Moreover the Lord your God will circumcise your heart and the heart of your descendants, to love the Lord your God with all your heart and with all your soul, in order that you may live. 7 And the Lord your God will inflict all these curses on your enemies and on those who hate you, who persecuted you. 8 And you shall again obey the Lord, and observe all His commandments which I command you today. 9 Then the Lord your God will prosper you abundantly in all the work of your hand, in the offspring of your body and in the offspring of your cattle and in the produce of your ground, for the Lord will again rejoice over you for good, just as He rejoiced over your fathers; 10 if you obey the Lord your God to keep His commandments and His statutes which are written in this book of the law, if you turn to the Lord your God with all your heart and soul.
Some would see this covenant as conditional based on the necessity of their conversion and obedience, however, we must view their conversion as a sovereign act of God. Indeed, it has been promised of God and will be all of His doing; nothing can reverse it; all Israel will be saved (Rom. 11:26-27).
