The Sinai Covenant

George Mendenhall (1954) and Klaus Baltzer (1971) demonstrated that the Sinai covenant follows the structure of second-millennium BC Hittite suzerainty treaties (treaties between a great king and his vassal states). The structure has six elements, all present in Exodus 19-24 and Deuteronomy:

(1) Preamble: identification of the great king, "I am the LORD your God" (Exodus 20:2a). (2) Historical prologue: what the great king has done for the vassal, "who brought you out of the land of Egypt, out of the house of slavery" (20:2b). The prologue precedes the law: grace precedes command. (3) Stipulations: the covenant requirements, the Ten Words (Decalogue, 20:3-17) and the Book of the Covenant (21-23). (4) Provision for deposit and periodic reading (Deuteronomy 31:9-13, the law to be read at the year of release). (5) List of witnesses, in Hittite treaties, the gods; in the Sinai covenant, heaven and earth (Deuteronomy 30:19, "I call heaven and earth to witness against you today"). (6) Blessings and curses (Deuteronomy 28, blessings for obedience, curses for disobedience).

The parallel with ANE treaty forms establishes that the Sinai covenant is a legal-political instrument, not merely a religious text. Israel becomes YHWH's vassal nation, bound to their Great King by treaty.

"Moses took the blood and threw it on the people and said, 'Behold the blood of the covenant that the LORD has made with you in accordance with all these words'" (Exodus 24:8). The ratification of the Sinai covenant involves blood: bulls are sacrificed, Moses reads the Book of the Covenant to the people, the people say "All that the LORD has spoken we will do, and we will be obedient" (24:7), and Moses throws half the blood on the altar and half on the people.

The blood seals the covenant: the altar represents YHWH, the people receive the blood on themselves, and together they are joined by the blood in covenant bond. The life (the blood, Leviticus 17:11 "the life of the flesh is in the blood") of the sacrificed animal seals the covenant between YHWH and Israel.

Jesus at the Last Supper directly echoes Exodus 24:8: "This cup is the new covenant in my blood, which is poured out for you" (Luke 22:20). The new covenant is ratified by the blood of Christ as the Sinai covenant was ratified by the blood of bulls, but the new covenant blood is "better" (Hebrews 9:23): the mediator of the new covenant (Hebrews 9:15) ratifies it with his own life.

The Sinai covenant and the Torah (the Law) are inseparable: the law is the covenant document, the constitution of the covenant people. This means the law is not a system of salvation by works, it is given to a people already redeemed from Egypt (the Exodus precedes Sinai; redemption precedes law). The law tells the redeemed people how to live as YHWH's covenant people.

Paul's analysis in Galatians 3:17: "the law, which came 430 years afterward (after the Abrahamic covenant), does not annul a covenant previously ratified by God, so as to make the promise void." The Abrahamic covenant was unconditional (YHWH alone passed through the cut animals, Genesis 15) and is the basis of the promise of the seed. The Sinai covenant adds the national law-structure for the people who will carry the promise, but it is added to, not in place of, the Abrahamic promise.

Galatians 3:19: "Why then the law? It was added because of transgressions, until the offspring should come to whom the promise had been made." The law was a temporary addition (the Greek word here is "added alongside") to make sin visible (Romans 3:20, "through the law comes knowledge of sin") and to function as a paidagogos (Galatians 3:24, guardian/escort) until Christ came. The Sinai covenant is provisional; the Abrahamic promise is permanent.

"not like the covenant that I made with their fathers on the day when I took them by the hand to bring them out of the land of Egypt, my covenant that they broke, though I was their husband, declares the LORD" (Jeremiah 31:32). YHWH's diagnosis of the Sinai covenant: it was broken. Israel repeatedly violated the covenant stipulations, worshiped other gods (the primary covenant violation, breaking the first commandment), and the curses of Deuteronomy 28 fell: exile to Babylon.

The Sinai covenant's problem was not the law itself, "the law is holy, and the commandment is holy and righteous and good" (Romans 7:12). The problem was the heart: "Did that which is good, then, bring death to me? By no means! It was sin, producing death in me through what is good" (Romans 7:13). The law was weak "through the flesh" (Romans 8:3), it revealed what was required but could not produce the inner transformation to meet the requirement.

Hebrews 8:7-8: "For if that first covenant had been faultless, there would have been no occasion to look for a second. For he finds fault with them when he says: 'Behold, the days are coming, declares the Lord, when I will establish a new covenant with the house of Israel and with the house of Judah.'" The fault was not the covenant document but the people's inability to keep it. The new covenant's solution: internalization, "I will put my law within them, and I will write it on their hearts" (Jeremiah 31:33).

The Sanctum reads the Sinai covenant not as a burden but as the constitution of the redeemed people, the Great King YHWH giving his vassal nation the terms of life in the land. The law is the gift of the covenant; the blood is the seal; the blessings and curses are the serious terms of the covenant life. The new covenant does not abolish the Sinai covenant's content, it fulfills it by writing the law on the heart through the Spirit (Ezekiel 36:26-27; Romans 8:3-4).
