“When we come into the land, you tie this scarlet cord in the window through which you are letting us down. Gather your father and mother, your brothers, and all your family into your house.”
Joshua 2:18 (NAB)
Rahab was a harlot, who helped hide two spies who Joshua sent to the city of Jericho. They were spying out the city with the plan to invade and take it over. After helping to hide the spies, she asked Joshua to save her and her family. Joshua promised to protect Rahab on the condition that she put a scarlet cord in her window, as a sign for his army. He assured her that his men would be told to spare the home with the scarlet cord in the window, and to harm no one inside. She gathered her parents and siblings together, put the scarlet cord in the window, and they all stayed inside the home. When the Israelite army took over the city, Rahab’s home was spared and her household was saved. She became a believer in the God of Israel and never returned to her harlot life. She married a soldier named Salmon from the tribe of Judah and had a son. Her son was named Boaz and he married Ruth, who was part of the family tree that carried on to David and finally to Jesus. Rahab changed her destiny, becoming an ancestor to Jesus, all because of a single scarlet cord.
In the story of the exodus from Egypt, Moses instructed families to put the lamb’s blood on their doorposts, so that when the angel of death saw the blood, he would pass over those homes and all the families inside were saved. God’s signs of salvation involve blood, only in Rahab’s case it was a scarlet cord, the color and symbol of blood. The blood of Jesus is like the scarlet cord in our window or the blood on our doorposts. It is God’s promise to us, a covenant in His blood. As Rahab trusted the scarlet cord, we trust in the blood of Jesus. Rahab and her family had to stay inside the home to be saved, as we need to abide in Jesus to be saved. God values our families as much as we do, and we learn from Rahab that we can intercede for our household’s salvation as Rahab did for hers. That scarlet cord was a sign of promise and the covenant Joshua made with her. Joshua’s very name is a variation of the name of Jesus, and both names mean salvation, which is no coincidence.
The story is a foreshadowing of the salvation promise that later came through Jesus. No one could imagine that a harlot would become an ancestor of the Messiah, but God imagined it, and still shows His mercy to anyone who will receive Him today. Rahab had faith in the promise, signified by a simple scarlet cord, and obediently stayed inside her house.
Jesus, we have faith in the blood shed by you on the cross, and as we stay in a relationship with you, please bring to pass all the wonderful plans you have imagined for us, our families and our household. Amen
