Why was blood required for the first covenant according to Hebrews 9:18? Immediate Context of Hebrews 9:18 Hebrews 9 contrasts the Sinai covenant with the new covenant in Christ. Verses 16-17 explain that a “diathēkē” (covenant or testament) is inaugurated by death; therefore, verse 18 states, “That is why even the first covenant was not inaugurated without blood” . The writer is drawing a legal and theological line: death had to be visually and ritually present for the covenant to take effect. Blood as Covenant Ratification in the Ancient Near East Across the Ancient Near East, covenants were sealed by sacrificial blood. Parties sometimes walked between divided carcasses (cf. Genesis 15:9-18) to symbolize, “May this happen to me if I break the oath.” Archaeological finds at Mari and Alalakh record animal-cutting ceremonies tied to treaty making. Israel’s adoption of a blood rite at Sinai fits this milieu yet uniquely magnifies holiness by directing the blood toward God on the altar (Exodus 24:4-8). “The Life of the Flesh Is in the Blood” (Leviticus 17:11) Blood represents life. God states, “I have given it to you upon the altar to make atonement for your souls” (Leviticus 17:11). To break covenant with the Holy One is to incur death; the life-blood of a substitute satisfies divine justice while preserving the people. This life-for-life principle undergirds every sacrificial act, culminating in Christ’s self-offering. Purification of People, Scroll, and Sanctuary Hebrews 9:19-21 recounts Exodus 24: Moses sprinkled half the blood on the altar (God’s side) and half on the people and the book of the covenant (human side). Blood therefore (1) consecrated the text itself, showing Scripture’s binding authority; (2) cleansed the worshipers, symbolizing forgiveness; and (3) dedicated the worship space and utensils, foreshadowing the heavenly sanctuary (Hebrews 9:23-24). Substitutionary Atonement Foreshadowed Every Levitical sacrifice—daily burnt offerings, the Passover lamb, the sin offering on Yom Kippur—echoed the truth that “without the shedding of blood there is no forgiveness” (Hebrews 9:22). These were shadows; Christ is the substance. “He entered the Most Holy Place once for all by His own blood, thus securing eternal redemption” (Hebrews 9:12). Legal Force: Death Brings a Testament into Effect In Greek, “diathēkē” can mean both covenant and last will. Hebrews leverages that dual sense: a will is activated by the death of the testator (Hebrews 9:16-17). The slain animals at Sinai served as a proxy death of the covenant maker; the covenant stood only because life had been poured out. Didactic Purpose: Demonstrating Sin’s Gravity and God’s Holiness Blood ceremonies shocked the senses. They impressed on Israel that sin is not a trivial mistake but a capital offense before a holy God. Behavioral science confirms vivid rituals have superior mnemonic power; they fix truth in communal memory, curbing moral drift (cf. Deuteronomy 6:20-25). Historical and Archaeological Corroboration • The altar complex uncovered at Tel Arad (8th century BC) shows blood channels consistent with Levitical prescriptions. • The Ketef Hinnom silver scrolls (7th century BC) contain the priestly blessing, demonstrating the cultic system Hebrews references was historically embedded. • Qumran’s Temple Scroll (11QT) outlines blood-based purification rites, corroborating Hebrews’ portrait of first-century Jewish understanding. These findings reinforce, rather than undermine, the scriptural account. Continuity from Eden to Calvary – Genesis 3:21: God clothes Adam and Eve with animal skins—first recorded bloodshed for sin cover. – Genesis 4:4: Abel’s accepted offering involves blood. – Genesis 22:13-14: Ram in Isaac’s place prefigures substitution. – Exodus 12:7-13: Passover blood shields from judgment. – Leviticus 16:15-19: Day of Atonement blood cleanses Israel. Each scene foreshadows the cross where “the Lamb who was slain” (Revelation 5:12) fulfills every type. Anticipation and Fulfillment in the New Covenant The first covenant’s blood requirement existed precisely to point beyond itself. Jeremiah 31:31-34 promised a new covenant of internal transformation. Jesus declared, “This cup is the new covenant in My blood” (Luke 22:20). What Sinai sign-posted, Calvary fulfilled: a single, perfect sacrifice, never to be repeated (Hebrews 10:10-14). Pastoral and Evangelistic Implications For the unbeliever, the Sinai blood rite shows the inescapable reality of moral accountability. If even the copies required blood, how much more the true heavenly things? For the believer, assurance rests not in repeated animal offerings but in a once-for-all, historically attested resurrection validating the cross. Trusting that provision is the sole pathway to reconciliation with the Creator and the ultimate purpose of life—glorifying God forever. Concise Answer Blood was required for the first covenant because life had to be surrendered to ratify the agreement, cleanse the participants, and foreshadow the ultimate, once-for-all atonement of Jesus Christ. |
