Jesus: From Genesis to Revelation

Day 2: Rahab's Faith and the Jordan Crossing

Reading

Historical Context

Joshua sends two spies from Shittim – the same location where Israel had fallen into idolatry with Moabite women (Numbers 25:1) – across the Jordan to Jericho. The Hebrew text is spare: “Go, view the land, especially Jericho” (Joshua 2:1). The mission echoes the earlier reconnaissance of Numbers 13, when twelve spies surveyed the land and ten returned with a report that paralyzed the nation. This time, only two are sent, and they end up not surveying fortifications or counting soldiers but hiding on a rooftop under stalks of flax, sheltered by a Canaanite prostitute.

Rahab’s house was built into the city wall – a common arrangement in ancient Near Eastern urban architecture, where the casemate wall system used the space between inner and outer walls as living quarters, often occupied by those on the margins of society. The Hebrew zonah identifies her plainly as a prostitute; some rabbinic traditions attempted to soften the term to “innkeeper,” but the New Testament preserves the original meaning without apology (Hebrews 11:31; James 2:25). Her occupation placed her at the lowest rung of Canaanite social order. Her location in the wall placed her, literally, at the boundary between the city and its destruction. She is liminal in every sense – socially, geographically, spiritually.

Rahab’s confession in Joshua 2:9-11 is remarkable for its theological precision. She has heard what God did at the Red Sea (yam suph) and what Israel did to Sihon and Og east of the Jordan. From these reports – secondhand, incomplete, filtered through the terror of her neighbors – she constructs a confession that exceeds anything the ten faithless spies of Numbers 13 managed: “The LORD your God, he is God in the heavens above and on the earth beneath” (Joshua 2:11). The phrase echoes the Shema’s exclusive monotheism. She has not seen the miracles. She has only heard. And she believes. The Hebrew shamanu (“we have heard”) in Joshua 2:10 is the same root as the great commandment: shema – “hear.”

The Jordan crossing in chapter 3 is narrated with deliberate echoes of the Red Sea. The priests carry the aron habberit – the ark of the covenant – into the river at flood stage. The text specifies the timing: “the Jordan overflows all its banks throughout the time of harvest” (Joshua 3:15). The river at its most impassable is the river God chooses to part. The moment the priests’ feet touch the water, the flow stops – the waters “rose up in a heap” at Adam, a town roughly twenty miles upstream. The language ned echad (“one heap”) is the same used in Exodus 15:8 to describe the Red Sea waters. The echo is unmistakable and intentional. What God did for the fathers, he does for the children. The Jordan becomes a second baptism – not of escape but of entry.

The ark goes first. The people follow at a distance of about two thousand cubits – roughly half a mile. They have never gone this way before (Joshua 3:4). The ark, which represents God’s presence and his covenant, leads them into unknown territory. The priests stand in the middle of the dry riverbed, holding the ark, while the entire nation crosses. God’s presence holds back the waters. The moment the priests’ feet leave the riverbed, the Jordan resumes its flow (Joshua 4:18). The crossing is sustained entirely by divine presence standing in the gap.

Christ in This Day

Rahab’s appearance in the genealogy of Jesus (Matthew 1:5) is one of the most theologically charged details in the New Testament. Matthew’s genealogy includes only five women, and three of them – Tamar, Rahab, and Ruth – are Gentiles. Rahab is not merely mentioned; she is identified as the mother of Boaz, who will marry Ruth, who will bear Obed, the grandfather of David, the ancestor of Christ. The scarlet cord she hangs from her window – the sign by which her household will be spared when Jericho falls – resonates with the blood on the doorposts at Passover (Exodus 12:7, 13). In both cases, a visible sign of faith marks a household for salvation while judgment falls on every side. The scarlet thread that saves Rahab’s family is woven, through the genealogy, into the bloodline of the Lamb of God. A Canaanite prostitute’s act of faith becomes a thread in the tapestry of redemption.

The New Testament cites Rahab in two different arguments, and both point to Christ. The author of Hebrews places her among the heroes of faith: “By faith Rahab the prostitute did not perish with those who were disobedient, because she had given a friendly welcome to the spies” (Hebrews 11:31). James cites her to demonstrate that faith without works is dead: “Was not also Rahab the prostitute justified by works when she received the messengers and sent them out by another way?” (James 2:25). These are not contradictory claims. They are complementary portraits of a woman who heard about God’s power, believed it, and acted on her belief at the risk of her life. She is the gospel before the gospel has a name: an outsider, a sinner, who is saved by grace through faith and incorporated into the people of God – and into the lineage of the King. Her story anticipates Paul’s declaration that “there is neither Jew nor Greek… for you are all one in Christ Jesus” (Galatians 3:28).

The Jordan crossing itself prefigures baptism. Paul writes that Israel was “baptized into Moses in the cloud and in the sea” (1 Corinthians 10:2) at the Red Sea. The Jordan extends the image: the people pass through the waters of death into the land of promise, led by the ark – the visible sign of God’s presence. Christian baptism enacts the same pattern. The believer descends into the water and rises to new life, following Christ – the true ark of the covenant – through death and into the inheritance. “Do you not know that all of us who have been baptized into Christ Jesus were baptized into his death? We were buried therefore with him by baptism into death, in order that, just as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life” (Romans 6:3-4). The Jordan is not merely a river to be crossed. It is a threshold between the old life and the new – between the wilderness of wandering and the land of promise. Christ stands in the middle of it, holding back the waters of judgment, until every last member of his people has passed through.

Key Themes

Connections

Old Testament Roots

The Jordan crossing echoes Exodus 14:21-22, where God divides the Red Sea and Israel crosses on dry ground. The language of waters standing “in a heap” (ned) appears in both the Song of the Sea (Exodus 15:8) and Joshua 3:13, 16 – a verbal link binding the two events. Rahab’s act of hiding the spies recalls the Hebrew midwives’ defiance of Pharaoh in Exodus 1:15-21: in both cases, women outside the covenant community risk their lives to protect God’s people, and God honors their faith. The scarlet cord (Joshua 2:18, tiqvat chut hashani) evokes the Passover blood on the doorposts (Exodus 12:7, 13).

New Testament Echoes

Matthew 1:5 places Rahab in the genealogy of Christ. Hebrews 11:31 celebrates her faith. James 2:25 cites her works as evidence of living faith. Romans 6:3-4 draws on the pattern of passing through water into new life – the same pattern enacted at the Jordan. 1 Corinthians 10:1-2 identifies the sea crossing as a kind of baptism, a typology the Jordan crossing extends.

Parallel Passages

Psalm 114:1-8 celebrates both the Red Sea and the Jordan in a single poem: “The sea looked and fled; Jordan turned back.” The two events are inseparable in Israel’s liturgical memory. Ruth 1-4 continues Rahab’s story through her descendants – Boaz, Obed, Jesse, David. Isaiah 43:2 extends the promise: “When you pass through the waters, I will be with you; and through the rivers, they shall not overwhelm you.”

Reflection Questions

  1. Rahab built her faith entirely on what she had heard about God – not what she had seen. How does her example challenge the assumption that faith requires personal experience of the miraculous? What “reports” of God’s faithfulness have shaped your own belief?

  2. The Jordan crossing deliberately echoes the Red Sea, proving to the second generation that God’s power has not diminished. Where in your life has God repeated a pattern of faithfulness that you had only heard about from a previous generation or season?

  3. Rahab was a Canaanite prostitute living in the wall of a condemned city – the most unlikely candidate for inclusion in the covenant community and the Messiah’s genealogy. Who are the people in your world whom you might overlook as candidates for God’s grace? What does Rahab’s story say about the boundaries of the gospel?

Prayer

God of the Red Sea and the Jordan, you are the one who makes a way through the waters – who parts what is impassable and holds back what would overwhelm. We thank you for Rahab, the unlikely woman whose faith shames our doubt, whose scarlet cord became a thread in the bloodline of your Son. We confess that we draw boundaries around your grace that you have never drawn, that we overlook the outsiders you are calling and cling to credentials you have never required. Teach us to believe what we have heard, as Rahab did – to stake our lives on the report of your faithfulness even when we have not yet seen it with our own eyes. And lead us, as you led Israel, through the waters and into the land of promise, following the ark of your presence into the life you have prepared for us. In the name of Jesus, the greater Joshua, who stands in the flood and holds back the waters until every last one of his people has crossed. Amen.
