Josué 2

Josué 2:21

A harlot saw this; and she who in the destruction of the city lost all hope of any means of safety, because her faith had conquered, bound a scarlet thread in her window, and thus uplifted a sign of her faith and the banner of the Lord's passion; so that the semblance of the mystic blood, which should redeem the world, might be in memory. So, from outside the city, the name of Joshua was a sign of victory to those who fought. From within, the semblance of the Lord's passion was a sign of salvation to those in danger. — Exposition of the Christian Faith 5.10.127
