Exodus 20

Exodus 20 records the foundational covenant constitution of Israel, known as the Decalogue, which establishes the moral law for God's redeemed people. The passage defines holiness not as a means to earn freedom, but as the expected response to Yahweh's prior act of deliverance from Egypt.

• The Theophany and Prologue: God identifies Himself as the Deliverer, providing the basis for the subsequent law (vv. 1-2).
• The First Table: Four commandments defining exclusive worship, reverence, and the Sabbath (vv. 3-11).
• The Second Table: Six commandments defining relational ethics and the sanctity of life, family, and property (vv. 12-17).
• The People's Fear: The Israelites, overwhelmed by the manifestation of God's holiness, request a mediator (vv. 18-21).
• Regulations for Worship: Commands concerning altars and purity in service to God (vv. 22-26).

• The 'I' [אָנֹכִי, H595] as the speaking subject who acts as Deliverer.
• The contrast between 'visiting iniquity' [עָוֺן, H5771] and 'showing mercy' [חֵסֵד, H2617].
• The imagery of 'thunders' and 'lightning' representing God's unapproachable majesty.
• The restriction against 'hewn stone' [H1696 usage implied for the act of crafting] to prevent human pride in worship.

This passage establishes the moral standard for the Old Covenant and reveals that the Law is an expression of God's character. In canonical context, it underscores the need for a mediator—a role pointing forward to Christ, the mediator of the New Covenant.

God's law is a covenantal gift, intended to structure the life of a people who have already been saved by grace, prioritizing absolute devotion to Him and love for the neighbor.

The text moves from the divine initiative of salvation (vv. 1-2) to the comprehensive demand for ethical living (vv. 3-17), before transitioning to the people's response and the practical protocols for acceptable worship (vv. 18-26).

• Showing mercy unto thousands of them that love me (v. 6)
• That thy days may be long upon the land (v. 12)
• In all places where I record my name I will come unto thee, and I will bless thee (v. 24)

• Thou shalt have no other gods before me (v. 3)
• Thou shalt not make unto thee any graven image (v. 4)
• Remember the sabbath day, to keep it holy (v. 8)
• Honour thy father and thy mother (v. 12)
• Thou shalt not kill (v. 13)
• Thou shalt not commit adultery (v. 14)
• Thou shalt not steal (v. 15)
• Thou shalt not bear false witness (v. 16)
• Thou shalt not covet (v. 17)

• Visiting the iniquity of the fathers upon the children (v. 5)
• The Lord will not hold him guiltless that taketh his name in vain (v. 7)
• Let not God speak with us, lest we die (v. 19)

• The event occurs at the foot of Mount Sinai after the Exodus from Egypt, establishing a suzerain-vassal relationship where the Great King (Yahweh) grants laws to His people (Israel).
• Matthew Henry observes that the law was originally written on the heart of man, but sin defaced it, necessitating the formal, external revelation of the Ten Commandments.

• The prohibition against 'graven images' [פֶּסֶל, H6459] stood in sharp contrast to the surrounding Ancient Near Eastern cultures where deities were localized and embodied in idols.
• The distinction between the 'first table' (duties to God) and 'second table' (duties to neighbor) reflects the ancient understanding that piety and ethics are inseparable.

• The Decalogue stands as the heart of the Book of the Covenant, acting as the moral foundation for the subsequent civil and ceremonial laws found in the following chapters.
• The repetition of the command against idolatry in verses 22-26 serves as an inclusio or emphatic conclusion to the moral section.

• The Sabbath command [v. 11] explicitly points back to the Genesis creation account, grounding the Sabbath in God's creative work.
• The New Testament later fulfills and expands the Decalogue (e.g., Jesus' Sermon on the Mount, Matthew 5-7), treating the law as a diagnostic of the heart rather than merely a checklist of external actions.
• Historical/Theological Debate: Regarding the nature of the Law, historic positions differ on its current application. Reformed theology often distinguishes between moral, ceremonial, and civil law, arguing the moral law remains binding; Dispensationalism often emphasizes the shift in administration, viewing the Law as a unit given to Israel that is not the direct 'rule of life' for the Church under grace. Both sides agree the Law remains inspired and authoritative Scripture.

• James 2:10 explicitly references the principle of the Decalogue: 'For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all.'
• Romans 13:9 identifies the summation of the second table of the law in the command to love one's neighbor.

• God [אֱלֹהִים, H430]: Elohim, a plural form emphasizing majesty and power, used here to declare the identity of the supreme Creator.
• Spoke [דָבַר, H1696]: This verb often implies the authoritative ordering of speech, signifying that these words are not suggestions but binding decrees.
• Jealous [קַנָּא, H7067]: Used exclusively of God, this term denotes a zeal for the exclusive relationship He has entered with His people; it is not human petty jealousy, but divine covenantal commitment.

• The preface (v. 2) occurs before any commandment; obedience is motivated by the memory of rescue, not the fear of punishment.
• The commandments are addressed to the community ('thou' is singular in Hebrew, representing the individual responsibility within the collective covenant).
• The instruction for altars (v. 25) prevents the worshiper from 'polluting' the altar with human craftsmanship, emphasizing that God's grace cannot be 'built' or 'improved' by human hands.

• There is variation in the enumeration of the commandments among Jewish, Catholic, and Protestant traditions (e.g., how the first and second commandments are divided or combined).
• Scholars debate the exact nature of the Sabbath in the New Covenant: whether it is a creation ordinance binding all, or a shadow fulfilled in the rest found in Christ.
