Jesus: From Genesis to Revelation

Day 2: The Shema and the Great Commandment

Reading

Historical Context

Moses’ second sermon begins with the restatement of the Ten Commandments in Deuteronomy 5 – the same decalogue given at Sinai (Horeb) a generation earlier, now delivered to the children of those who stood at the mountain’s base. The Hebrew torah in the chapter heading (4:44) does not mean “law” in the narrow, legislative sense that English speakers often assume. Torah derives from the root yarah, “to instruct, to point the way.” It is direction, teaching, guidance – the kind of instruction a father gives a child, not the kind a bureaucrat issues from an office. This distinction matters because everything that follows in Deuteronomy 5-6 is addressed not to subjects of a distant sovereign but to children of a present father. The voice is intimate, urgent, and personal.

The restatement of the Ten Commandments in chapter 5 is nearly identical to the Exodus 20 version, with one significant difference. The motivation for the Sabbath command shifts: in Exodus 20:11, the Sabbath is grounded in creation (“for in six days the LORD made heaven and earth”); in Deuteronomy 5:15, it is grounded in redemption (“You shall remember that you were a slave in the land of Egypt, and the LORD your God brought you out”). The same command, two reasons. Creation and exodus. The God who rested after making the world is the God who liberates slaves and gives them rest. For the generation on the plains of Moab – children of slaves, born in the wilderness – the redemptive rationale is the one that cuts closest to the bone.

Deuteronomy 5:22-27 records the people’s response to the theophany at Horeb: “The LORD our God has shown us his glory and greatness, and we have heard his voice out of the midst of the fire… Let us not die… You go near and hear all that the LORD our God will say, and speak to us all that the LORD our God will speak to you, and we will hear and do it” (5:24-27). The people cannot endure the unmediated presence of God. They beg for a mediator – someone who will stand between the fire of God’s holiness and the fragility of their flesh. Moses is that mediator. But the request itself creates a trajectory: if the people need someone to stand between them and God, then the mediatorial office Moses holds is not a temporary arrangement but a permanent necessity. The prophet like Moses (18:15) is already being anticipated.

Then comes the Shema: “Hear, O Israel: The LORD our God, the LORD is one. You shall love the LORD your God with all your heart and with all your soul and with all your might” (6:4-5). The opening verb shema means far more than auditory reception. In Hebrew, to hear is to obey, to respond, to internalize. The declaration YHWH Elohenu YHWH echad – “the LORD our God, the LORD is one” – is grammatically ambiguous and theologically inexhaustible. The word echad (“one”) can mean “alone,” “unique,” or “unified.” It is both a confession of monotheism – there is no other God – and a demand for exclusive allegiance – there must be no other loyalty. The love that follows is not sentimental. The Hebrew ‘ahavah in covenantal contexts denotes loyalty, faithfulness, and total commitment. In ancient Near Eastern treaty language, “to love” the suzerain meant to serve him exclusively, to put his interests above all others. The three terms that define the scope of this love – levav (heart, the seat of will and decision), nephesh (soul, the whole person, life itself), and me’od (might, “very-ness,” everything you possess) – leave no remainder. Nothing is exempt. Nothing is reserved.

Moses immediately translates the Shema into domestic practice: “You shall teach them diligently to your children, and shall talk of them when you sit in your house, and when you walk by the way, and when you lie down, and when you rise” (6:7). The verb shinnan (“teach diligently”) comes from a root meaning “to sharpen” or “to repeat.” The word is not pedagogical in the classroom sense but formational in the atmospheric sense – the way a whetstone shapes a blade through repetitive contact. God’s words are to be bound on the hand (yadekha), placed between the eyes (bein ‘einekha), and written on the doorposts (mezuzot). Later Jewish tradition took this literally, producing tefillin (phylacteries) and mezuzot. But the principle is universal: God’s word must be so close to the believer that it shapes every action (hands), every perception (eyes), and every threshold crossed (doorposts). The instruction is total. The life of faith is not a compartment but an atmosphere.

Christ in This Day

When a lawyer asks Jesus to name the greatest commandment, Jesus does not hesitate. He quotes the Shema: “You shall love the Lord your God with all your heart and with all your soul and with all your mind” (Matthew 22:37). Then he adds Leviticus 19:18 – “You shall love your neighbor as yourself” – and makes a claim of breathtaking authority: “On these two commandments depend all the Law and the Prophets” (Matthew 22:40). The Greek kremannumi (“depend, hang”) is the word used for hanging something on a hook or peg. Jesus takes the entire Old Testament – every statute, every prophecy, every narrative – and hangs it on two sentences. Only the author of the law has the authority to summarize it this way. The Pharisees do not argue. They cannot. The answer is perfect, and its perfection is the tell: the one who can reduce the Torah to its essence without losing a syllable of its meaning is the one who gave it in the first place.

But Jesus does not merely teach the Shema. He fulfills it. In the wilderness temptation, all three of Jesus’ responses to Satan come from Deuteronomy – and specifically from the section of Deuteronomy that surrounds the Shema. “Man shall not live by bread alone, but by every word that comes from the mouth of God” (Matthew 4:4; Deuteronomy 8:3). “You shall not put the Lord your God to the test” (Matthew 4:7; Deuteronomy 6:16). “You shall worship the Lord your God and him only shall you serve” (Matthew 4:10; Deuteronomy 6:13). The wilderness temptation is a Shema test. Where Israel failed in the wilderness – craving bread, testing God at Massah, worshiping the golden calf – Jesus succeeds. He loves God with all his heart by refusing to turn stones to bread when his body is starving. He loves God with all his soul by refusing to test the Father’s faithfulness with a theatrical plunge from the temple. He loves God with all his might by refusing Satan’s offer of every kingdom in the world. Jesus is the first and only human being to keep the Shema completely – from the wilderness to Gethsemane, where “not my will, but yours, be done” (Luke 22:42) is the Shema prayed in blood.

The people at Horeb begged for a mediator: “You speak to us, and we will listen; but do not let God speak to us, lest we die” (Exodus 20:19; cf. Deuteronomy 5:25-27). Moses became that mediator – standing between God’s consuming holiness and the people’s terrified fragility. But Moses was himself a sinner, excluded from the Promised Land for his own failure. The New Testament identifies Jesus as the mediator the people needed but Moses could only foreshadow: “For there is one God, and there is one mediator between God and men, the man Christ Jesus” (1 Timothy 2:5). The author of Hebrews develops the comparison at length: “Jesus has been counted worthy of more glory than Moses – as much more glory as the builder of a house has more than the house itself” (Hebrews 3:3). Moses was faithful in God’s house as a servant. Christ is faithful over God’s house as a son. The mediatorial office that began at Horeb finds its permanent occupant at Calvary, where the one who stands between God and humanity does not merely relay the word but is the Word (John 1:1).

Key Themes

Connections

Old Testament Roots

The Ten Commandments restated in Deuteronomy 5 are rooted in the original Sinai revelation of Exodus 20:1-17. The shift in Sabbath motivation – from creation (Exodus 20:11) to redemption (Deuteronomy 5:15) – reflects the complementary theological foundations of Israel’s rest. The Shema’s demand for exclusive love echoes the first commandment (“You shall have no other gods before me,” Exodus 20:3) and the covenant formula of Exodus 34:14: “The LORD, whose name is Jealous, is a jealous God.” The instruction to teach children (Deuteronomy 6:7) extends the patriarchal mandate of Genesis 18:19, where God says of Abraham, “I have chosen him, that he may command his children and his household after him to keep the way of the LORD.”

New Testament Echoes

Jesus quotes the Shema as the greatest commandment in Matthew 22:37-40 and Mark 12:29-31. In Mark’s account, the scribe who asked the question agrees – “You are right, Teacher. You have truly said that he is one, and there is no other besides him” – and Jesus responds, “You are not far from the kingdom of God” (Mark 12:32-34). Paul echoes the Shema in 1 Corinthians 8:6: “Yet for us there is one God, the Father, from whom are all things and for whom we exist, and one Lord, Jesus Christ, through whom are all things and through whom we exist” – a reformulation that places Christ within the identity of the one God Israel confesses. The wilderness temptation (Matthew 4:1-11) is a sustained engagement with the Deuteronomy 6-8 passage, with Jesus demonstrating the Shema obedience that Israel could not sustain.

Parallel Passages

Joshua 22:5 – “Be very careful to observe the commandment and the law… to love the LORD your God, and to walk in all his ways and to keep his commandments and to cling to him and to serve him with all your heart and with all your soul” – repeats the Shema language as Joshua passes the torch. 2 Kings 23:25 applies it to Josiah: “Before him there was no king like him, who turned to the LORD with all his heart and with all his soul and with all his might, according to all the Law of Moses.” Yet even Josiah’s faithfulness could not avert the exile – a reminder that the Shema awaits its ultimate fulfillment in one greater than any king.

Reflection Questions

  1. The Shema demands love with all the heart, all the soul, all the might – nothing compartmentalized, nothing reserved. Where in your life do you sense a divided allegiance – an area where you give God partial loyalty while holding something back for a rival? What would it look like to bring that area under the Shema’s totalizing claim?

  2. Moses commands Israel to teach God’s words “when you sit in your house, and when you walk by the way, and when you lie down, and when you rise.” This is atmospheric, not periodic. How does this vision challenge a once-a-week approach to spiritual formation? What practical step could you take this week to make God’s word more atmospheric in your daily life?

  3. Jesus passed the Shema test in the wilderness where Israel failed. He loved God with all his heart (refusing bread), all his soul (refusing the temple stunt), all his might (refusing the kingdoms). How does knowing that Jesus has perfectly fulfilled the commandment you cannot keep change the way you relate to God’s demands? Does it produce despair or freedom – and why?

Prayer

O LORD our God, the LORD is one. There is no other God, no other allegiance, no other claim on our hearts that can stand beside yours. We confess that we have divided what you demand to be whole – offering you a fraction of our love while scattering the rest among rivals that cannot save. Forgive us. Gather our fragmented hearts and make them undivided before you. Thank you for Jesus, who in the wilderness loved you with all his heart when his body was starving, all his soul when the tempter offered a shortcut, all his might when every kingdom of the world was laid at his feet. He kept the Shema we have broken. He fulfilled the love we cannot sustain. Write your word on our hearts as Moses commanded it be written on doorposts and bound on hands – not as external obligation but as the atmosphere we breathe, the truth we teach our children, the confession we carry from the moment we rise until the moment we rest. In the name of the one Mediator between God and humanity, Christ Jesus our Lord. Amen.
