So she [Rahab] let them down by a rope through the window, for the house she lived in was part of the city wall. Joshua 2:15
The story of Rahab, described as a harlot in Jericho, is told in Joshua chapters 2 and 6. She hid the Israelites who were spying out the city and in doing so saved herself and her family. In Hebrews 11:31 it says that Rahab did this by faith. She decided to put her faith and life in the hands of this wonder-working God she had heard of.
Rahab, and her actions hiding the Israelite spies, is mentioned twice in the New Testament as an example of faith showing itself in good works. But, did you know that Rahab was the great-great grandmother of King David, and therefore in the genealogy of Jesus?
But Joshua spared Rahab the prostitute, with her family and all who belonged to her, because she hid the men Joshua had sent as spies to Jericho—and she lives among the Israelites to this day. Joshua 6:25
A record of the genealogy of Jesus Christ the son of David, the son of Abraham … Salmon the father of Boaz, whose mother was Rahab, Boaz the father of Obed, whose mother was Ruth, Obed the father of Jesse, and Jesse the father of King David. Matthew 1:1, 5-6
Here’s some commentary on Rahab’s marriage to Salmon:
The Old Testament records are silent as to the marriage of Salmon with the harlot of Jericho. When they were compiled it was probably thought of as a blot rather than a glory; but the fact may have been preserved in the traditions of the house of David. It has been conjectured that Salmon may have been one of the two unnamed spies whose lives were saved by Rahab, when he was doing the work which Caleb had done before him. The mention of Rahab in James 2:25, Hebrews 11:31, shows that her fame had risen at the time when St. Matthew wrote. —Elliott’s Commentary for English Readers (emphasis mine)
I always thought that this was why Boaz had no qualms about marrying a despised Moabite, Ruth (see Ruth chapters 1-4), because his own mother was a Canaanite outcast. Both Rahab and Ruth had converted and chosen to follow the God of Abraham, Isaac, and Jacob. What is so wonderful is that these two foreigners and outsiders are prominent in the family tree of Jesus (see Matthew 1:1-16).
And they are not the only ones in the genealogy that raise eyebrows. There is Tamar, who pretended to be a prostitute to lure Judah into obeying the command of God. There is Bathsheba, whose extramarital tryst resulted in an unplanned pregnancy and the murder of her husband. Not to mention Mary, who became pregnant out of wedlock. And that’s just the women. There was also David, who committed the murder of Bathsheba’s husband, Ahaz who sacrificed his children to false gods, and Manasseh, about whom it is written that he “shed so much innocent blood that he filled Jerusalem from end to end.”
You know that saying, “you can choose your friends, but you can’t choose your family”? Well, God could have. God could have arranged that Jesus be born of a spotless, totally righteous bloodline of perfect people. But he did not.
Martyn Lloyd-Jones has written that when Jesus left heaven “he left heaven as God, God the Son, but when he returned to heaven he was God and Man. He has taken human nature with him.”1 How wonderful! How amazing! Right from the start, and on into eternity, God, through Jesus, embraces humanity, embraces the sinner – even the most horrible, detestable of sinners. By taking on human nature and living a perfect human life, Jesus has made a Way to take us back to heaven with and in him.
Rahab’s scarlet cord, that she tied in the window to ward off the attackers, was a foreshadowing of salvation by the atoning death, the shed blood, of Jesus. Ruth laying down at the feet of Boaz and asking him to marry her is a picture of Christ and the Bride, the Church. Do you see the message of grace and mercy printed right into the DNA of Jesus?
It doesn’t matter what you have done, you can come to God and be accepted into the family through the blood of Jesus shed for you. Turn from your sin. Put your faith in what He did for you on the cross. Bow down at his feet as Ruth did. He wants to receive you, cleanse you, save you, and marry you as the holy Bride of Christ, the Church.
