“The rest of the people—priests, Levites, gatekeepers, musicians, temple servants and all who separated themselves from the neighboring peoples FOR THE SAKE OF THE LAW OF GOD. together with their wives and all their sons and daughters who are able to understand— all these now join their fellow Israelites the nobles, and BIND THEMSELVES WITH A CURSE AND AN OATH to follow THE LAW OF GOD GIVEN THROUGH MOSES the servant of God and TO OBEY CAREFULLY ALL THE COMMANDS, REGULATIONS, AND DECREES of the Lord our Lord” (Nehemiah 10:28-29).
Why did these Israelites, who were returning for the Babylonian captivity, bind themselves with a curse? It is because they were dedicating themselves to God and to the covenant God made with their fathers through Moses.
The Law of Moses was accompanied with a curse (aka, the curse of the law). The Law of Moses was a binding covenant on the nation of Israel and being a partaker of that covenant meant being subjected to the curse for not doing all that the law demands.
This is precisely why Paul warns the believers in Galatia not seek justification by the works of the law, because the curse accompanies the law. The law demands the continuation in the works of the Law to all who are under it and therefore all who do not continue in all things contained in the law are under a curse.
You cannot separate the curse from the law covenant given through Moses. Those who attempt to do so are guilty of trespassing the very law they claim to obey. They claim they are not under the curse, while at the same time claiming that the law is still binding. Yet, the law itself says, “Cursed is everyone who does not continue to do everything written in the Book of the Law.”
Those who teach such error by putting others under their private interpretations of the law often excuse themselves for not keeping all the Law which the law itself actually demands. In this they reinvent the law with the portions they deem enforceable.
The Law of Moses was a unit, and not some divided up thing that some have made it into. Yet some have turned it into something that the Bible never reveals it to be. It was never a broken up dysfunctional system. According to the Holy Scriptures the Law Covenant was first ratified with the blood of animals, then the Law was given, then the priesthood, the sacrificial system, the various statutes and ordinances including the festivals were put in place and served as rule of life and constitution for the people of Israel in the flesh.
These were all interlinked and you cannot have one without the other. If any part of this covenant is obsolete, it is all obsolete. You do not, and cannot have the Law covenant without the blood of animals, the Levitical priesthood, the tabernacle/temple, the brazen altar, the laver, the lamp stand, the table of shew bread, the golden altar, and the Ark of the Covenant.
Jesus died and rose again, not to keep a remnant of the Law covenant in place, but to give us a better covenant established on better promises.
