Jesus: From Genesis to Revelation

Day 3: The Book of the Covenant Begins -- Altars, Slaves, Violence, and Justice

Reading

Historical Context

The transition from the Decalogue to the Book of the Covenant marks a shift from apodictic law – absolute commands stated without qualification (“You shall not”) – to casuistic law – case law framed as conditional statements (“If a man does X, then Y”). This form of legal reasoning was common throughout the ancient Near East. The Code of Hammurabi (c. 1750 BC), the Laws of Eshnunna (c. 1930 BC), and the Hittite law codes all employ casuistic formulations. Israel was not the first culture to develop case law. But the theological framework within which Israel’s laws operate is radically different. In Mesopotamia, the king promulgated law as an expression of his own authority and wisdom. In Israel, the law comes directly from God, and Moses is merely the conduit. The source of justice is not a human throne but a divine voice still echoing from the mountain.

The altar law (Exodus 20:24-26) opens the Book of the Covenant with a striking restriction: altars must be made of earth or unhewn stone. “If you make me an altar of stone, you shall not build it of hewn stones, for if you wield your tool on it you have profaned it” (ki charbeka henafta aleha). The Hebrew word for “tool” here is chereb – the same word used for “sword.” Human craftsmanship, associated with violence and self-assertion, must not touch the place where God meets his people. The altar is God’s territory, not a showcase for human skill. The prohibition against steps (Exodus 20:26) – “that your nakedness be not exposed on it” – addresses both dignity and the avoidance of pagan practices, where ritual nudity was common in Canaanite worship.

The slave laws of Exodus 21:1-11 are among the most debated passages in the Old Testament. The Hebrew term eved covers a broad range of meaning – from chattel slave to indentured servant to court official. In Israel’s case law, the eved ivri (Hebrew servant) is typically a person who has sold himself into service to pay a debt, and the law limits his term to six years. The seventh year, he goes free (chofshi) – and the vocabulary of freedom deliberately echoes the Sabbath pattern. Just as the seventh day is rest from labor, the seventh year is release from bondage. The law does not abolish the institution of servitude – an impossibility in the ancient economy – but it radically limits it, humanizes it, and inscribes liberation into its very structure.

The case of the servant who chooses to stay (Exodus 21:5-6) is particularly striking. At the end of his six-year term, if the servant declares, “I love my master, my wife, and my children; I will not go out free,” his master brings him to the doorpost and pierces his ear with an awl (martseah). The pierced ear is a mark of permanent, voluntary devotion – servitude chosen out of love, not compulsion. The early church fathers recognized in this image a portrait of Christ, who, “though he was in the form of God, did not count equality with God a thing to be grasped, but emptied himself, by taking the form of a servant” (Philippians 2:6-7). The free one who chooses bondage out of love.

The laws governing violence (Exodus 21:12-36) – murder, manslaughter, assault, injury to slaves, the goring ox – reveal a legal system built on the principle of proportional justice. The famous lex talionis – “eye for eye, tooth for tooth, hand for hand, foot for foot” (Exodus 21:24) – is often misread as primitive vengeance. In its original context, it was a limitation on vengeance. In a world where tribal feuds could escalate a single injury into a generational war, the lex talionis said: the punishment must match the crime, no more. It was a ceiling, not a floor. Justice, not revenge.

Christ in This Day

The servant who refuses freedom because he loves his master is one of the most vivid Christological images in the Torah. The writer of Hebrews quotes Psalm 40:6-8, placing the words in the mouth of Christ: “Sacrifices and offerings you have not desired, but a body you have prepared for me… Then I said, ‘Behold, I have come to do your will, O God’” (Hebrews 10:5-7). Christ enters the world as the willing servant – not compelled, not enslaved, but voluntarily binding himself to the Father’s purpose and to his people’s need. The pierced ear at the doorpost becomes the pierced hands and feet at the cross. Both are marks of love that chooses not to go free. Paul understood this when he called himself a doulos Christou Iesou – a bondservant of Christ Jesus (Romans 1:1). The term doulos is not metaphorical. It is the Greek equivalent of eved. Paul has been to the doorpost. His ear is pierced. He will not go out free, because he has found in Christ a master worth serving forever.

The lex talionis – “eye for eye, tooth for tooth” – is the passage Jesus directly engages in the Sermon on the Mount: “You have heard that it was said, ‘An eye for an eye and a tooth for a tooth.’ But I say to you, Do not resist the one who is evil. But if anyone slaps you on the right cheek, turn to him the other also” (Matthew 5:38-39). Jesus does not contradict the principle of proportional justice. He transcends it. The lex talionis was a limit on human vengeance – punishment proportional to the offense. Jesus calls his followers beyond proportional justice to absorptive grace – bearing the cost of evil rather than returning it. This is not weakness. It is the logic of the cross. On Calvary, the one to whom all vengeance rightly belongs absorbed the full weight of human sin rather than returning it measure for measure. He took the eye, the tooth, the hand, the life – and gave back forgiveness. The servant law and the injury law converge in Christ: the free one who chose bondage, the just one who absorbed injustice, the one who had every right to go free and every right to strike back – and did neither, because love held him to the doorpost and love held him to the cross.

The altar law – unhewn stone, no human tool, no steps for human ascent – points to the nature of the sacrifice Christ would become. Human craftsmanship cannot improve the place where God meets sinners. Human effort cannot build a stairway to divine acceptance. The altar must be raw, unadorned, untouched by the sword of human achievement. Christ is that altar – or more precisely, Christ is both the altar and the offering. “We have an altar from which those who serve the tent have no right to eat” (Hebrews 13:10). The place of meeting between God and humanity is not a monument to human skill. It is a cross of rough wood, unhewn by human righteousness, where the Lamb of God was offered once for all.

Key Themes

Connections

Old Testament Roots

The altar law echoes Genesis 8:20, where Noah builds an altar after the flood – the first act of worship in the renewed world. The slave laws are grounded in Israel’s own experience of bondage: “Remember that you were a slave in the land of Egypt” (Deuteronomy 15:15). The lex talionis appears again in Leviticus 24:19-20 and Deuteronomy 19:21, consistently functioning as a limit on excessive punishment. The doorpost imagery of Exodus 21:6 echoes the Passover doorpost of Exodus 12:7, where blood on the doorframe marked the boundary between death and life.

New Testament Echoes

Philippians 2:5-8 – Christ takes the form of a servant (doulos) and humbles himself to death on a cross. Hebrews 10:5-7 – Christ enters the world saying, “A body you have prepared for me… I have come to do your will.” Matthew 5:38-39 – Jesus transcends the lex talionis with the call to absorb evil rather than return it. Galatians 5:13 – “Through love serve one another,” the ethic of voluntary servitude applied to the whole community.

Parallel Passages

The Code of Hammurabi (Laws 196-200) contains a parallel lex talionis, but applies it only among social equals – injuries to slaves or lower classes receive lesser penalties. Israel’s law, while not perfectly egalitarian by modern standards, moves significantly toward equal protection: “If a man strikes the eye of his slave, male or female, and destroys it, he shall let the slave go free because of his eye” (Exodus 21:26). Deuteronomy 15:12-18 revisits the slave laws with an explicit command to provide generously for the departing servant.

Reflection Questions

  1. The altar must be unhewn stone – no human tool, no human craftsmanship. What does this say about the nature of worship? Where in your own spiritual life are you tempted to improve the altar with your own tools – your performance, your eloquence, your effort?

  2. The servant who stays out of love, whose ear is pierced at the doorpost, is a picture of Christ. It is also a picture of discipleship. What would it look like for you to say, “I love my master; I will not go out free”? What keeps you from that kind of voluntary, wholehearted devotion?

  3. Jesus takes the lex talionis – a law designed to limit vengeance – and calls his followers to absorb evil rather than return it. Where in your life is God asking you to move beyond proportional justice to absorptive grace?

Prayer

Lord God, you descended from the thunder of the ten words into the dirt of daily life – oxen and servants and doorposts and injuries. You care about the details of how we live together, because justice in the small things reveals whether we have understood your holiness at all. We thank you for the servant who stayed – who loved his master and would not go free – and we recognize in his pierced ear the shadow of your Son’s pierced hands. Jesus, you were free and chose bondage. You were just and absorbed injustice. You stood at the doorpost of the cross and declared your love for us with wounds that will never close. Make us servants like you – not compelled by duty but drawn by love, not building altars of our own craftsmanship but resting on the unhewn stone of your finished work. Teach us proportional justice and, beyond it, the costly grace that absorbs rather than retaliates. In your pierced and risen name. Amen.
