The Covenant chapter follows the spine that holds the Old Testament together. After Eden, Scripture does not record an abstract relationship between God and humanity; it records a series of covenants — formal, named, structured arrangements by which the LORD binds Himself to a people and gives them a way to belong to Him. The covenants do not replace each other; they layer. Paul argues exactly this in Galatians 3 — the Mosaic law given four centuries after Abraham does not annul the Abrahamic promise. Each cutting adds without erasing.
The first covenant after the flood is with Noah and his family — and through them with every living creature on the earth (Gen 9:8-17). Its sign is the rainbow set in the cloud, its content is the promise that the waters will never again destroy all flesh, and its scope is universal. Long before there is an Israel, the LORD has covenanted with the world. The Noahic covenant is the floor under every later covenant: the assurance that creation will continue while redemption proceeds.
The Abrahamic covenant is the chapter's center of gravity. In Genesis 12 the LORD calls Abram out of Ur and gives him a triple promise — land, descendants, and blessing-to-the-nations. The triple shape matters: Israel will be a particular people in a particular land, but the particularity is for the sake of the nations, not against them. Genesis 15 ratifies the covenant in the strange ceremony of the halved animals; Genesis 17 gives circumcision as the bodily sign; Genesis 22 brings Abraham and Isaac to Mount Moriah for the binding that will become, in Christian reading, the type of every sacrifice that follows.
Mount Moriah is one of the chapter's pivot points. 2 Chronicles 3:1 identifies it as the location of Solomon's temple. Christian tradition has long read the same hill — and by extension the larger Jerusalem geography — as the place where Christ's sacrifice would ultimately be offered. The Atlas treats this identification with care. Scripture explicitly names Moriah as the binding site and as the Temple Mount. The further connection to Golgotha is a typological reading the church has held since the early centuries; it is theologically rich and historically defensible, but the exact topographical correspondence between Genesis 22 and the crucifixion site involves both biblical witness and traditional interpretation. The Atlas labels each layer for what it is.
The Mosaic covenant gives Israel a national structure. The Ten Words at Sinai, the Book of the Covenant in Exodus 21–23, the priestly arrangements of Leviticus, and the wilderness institutions of Numbers together constitute a way of life — a polity, a liturgy, a law code — by which Israel can be holy. The covenant is ratified at Sinai with blood: Moses reads the words, the people answer that they will do them, and the blood of bulls is sprinkled on the altar and on the people (Ex 24). Word and blood together. Hebrews 9 will read this scene as the template for the New Covenant in Christ's blood.
The Davidic covenant in 2 Samuel 7 narrows the focus to a single dynasty. The LORD promises David that one of his descendants will sit on his throne forever — a promise that becomes the spine of every messianic hope in the prophets, the Psalms, and the post-exilic literature. The Davidic covenant is the bridge between the Mosaic law (a people under a king) and the New Covenant (a king who is also the high priest and the sacrifice). Without 2 Samuel 7 there is no Matthew 1.
Jeremiah 31 names the covenant the prophets had been reaching toward: a new covenant, not like the one made with their fathers, when the LORD will write His law on hearts and forgive iniquity and remember sin no more. The new covenant is not a replacement for what came before so much as the fulfillment of what every prior covenant was straining toward. The blood of bulls cannot finally take away sin (Heb 10:4); the law written on tablets cannot reach the human heart from the outside. The new covenant addresses both gaps from the inside.
Jesus at the Last Supper deliberately echoes Exodus 24. This is My blood of the covenant, He says, which is poured out for many for the forgiveness of sins (Mt 26:28). The same Greek phrasing the Septuagint used at Sinai is now applied to the cup. Hebrews 9 spells the implication out — the first covenant was inaugurated by blood, so the second; but the blood of Christ is better than the blood of bulls and goats, and the covenant it ratifies is the one that endures.
The chapter pays particular attention to the geography. Each covenant has a place: Ararat for Noah, Ur and Canaan and Moriah for Abraham, Sinai for Moses, Jerusalem for David, the upper room and Calvary for Christ. The Atlas maps these as a single line connecting the eastern landfall of the ark to the western ascent of Christ — the slow westward redemptive arc that began at Babel and ends in the New Jerusalem. The covenants are not just legal arrangements; they are bound to land.
Chapter 3 closes with a survey of the sacrificial system as the covenant's bloodstream. The Passover lamb of Exodus 12, the Day of Atonement of Leviticus 16, the daily morning-and-evening offerings, the firstfruits and the booths and the trumpets — each of these is read by Hebrews and the rest of the New Testament as a typological pre-enactment of Christ. Not a parallel system to be retired but a shadow whose substance has come. The covenants are kept, finally, in a person.
