“And she sent them away, and they departed. And she bound the scarlet cord in the window” (Joshua 2:21 NKJV)

Rahab, the Jericho harlot, hid the Israelite spies whom Joshua had sent to reconnoiter the city. After making an amazing confession of faith in the Lord, she made a deal with the spies that she would hide them in return for protecting her family when the Lord gave the city over to Israel. The spies agreed. They told her to hang a “scarlet cord in the window” of her house to identify it and to keep everyone inside the house, otherwise they would not be responsible for them.
The “scarlet cord” reminds me of the blood of the lamb that was applied to the doors of the Israelites’ homes in Egypt, so that the angel of death would pass over them. It also reminds me of the blood of the Lamb of God, Jesus Christ, which was shed, so that those who trust in Him might live.
Rahab’s family was spared when Israel destroyed Jericho. Those inside the house with the “scarlet cord in the window” were saved. Rahab and her family became part of God’s people. So that, even Rahab was listed in Matthew’s genealogy of Christ (Matt. 1:5).
Do you have a “scarlet cord” hanging from your window?
