Rahab's Scarlet Cord (Josh 2)

Full Josh 2:15–21 with 6:22–25. Rahab ties a scarlet cord (Hebrew tiqvat hashani, literally the hope of scarlet; the same root as hope/cord) in her window; every person inside is spared. Patristic tradition (Justin Martyr, Dialogue with Trypho 111; Clement of Rome, 1 Clement 12) reads the cord as a type of Christ's blood. Rahab is named in Matt 1:5 as an ancestor of the Messiah.
