The window which thou didst let us down by. — It seems almost needless to observe that the scarlet line and the cord by which the men were lowered are not the same thing, but described by different words in the original. It would have been preposterous to require Rahab to display in her window the means by which the spies had escaped. It would at once have declared the tale to all beholders — the very thing Rahab was pledged not to do. The “line of scarlet thread” and the “stalks of flax” on the roof were probably parts of the same business, and thus there would be nothing unusual in what was exhibited at the window, although it would be a sufficient token to those who were in the secret, to enable them to identify the house.
