Behold, when we come into the land, thou shalt bind this line of scarlet thread in the window which thou didst let us down by: and thou shalt bring thy father, and thy mother, and thy brethren, and all thy father's household, home unto thee.
The instruction—'Behold, when we come into the land, thou shalt bind this line of scarlet thread in the window'—provided salvation's visible marker. The scarlet cord identifies Rahab's house, sparing all within during Jericho's destruction. This parallels Passover's blood on doorposts (Exodus 12:13), where visible sign protected occupants from judgment. Both foreshadow Christ's blood marking believers for salvation from wrath (Romans 5:9). External signs confirm internal faith while providing community-visible testimony.
Historical Context
The scarlet thread became covenant sign between Rahab and the spies. Its color—red like blood—anticipates Christ's blood covenant. Rahab's window location in the wall provided escape for the spies and later identification for Israel's army. Some traditions identify this Rahab with Salmon's wife (Matthew 1:5), making her David's ancestor and ultimately Christ's. The thread's continued display until conquest demonstrates faith's perseverance—Rahab maintained hope through Jericho's siege.
