Josua 2:15

Rahab then let them down by a rope through the window, namely, into the open country; for her house stood against or upon the town wall, so that she lived upon the wall, and advised them to get to the mountains, that they might not meet the men who had been sent out in pursuit of them, and to hide themselves there for three days, when the pursuers would have returned.

In this chapter we have an account of the scouts that were employed to bring an account to Joshua of the posture of the city of Jericho. Observe here, I. How Joshua sent them (v. 1). II. How Rahab received them, and protected them, and told a lie for them (v. 2-7), so that they escaped out of the hands of the enemy. III. The account she gave them of the present posture of Jericho, and the panic-fear they were struck with upon the approach of Israel (v. 8-11). IV. The bargain she made with them for the security of herself and her relations in the ruin she saw coming upon her city (v. 12-21). V. Their safe return to Joshua, and the account they gave him of their expedition (v. 22-24). And that which makes this story most remarkable is that Rahab, the person principally concerned in it, is twice celebrated in the New Testament as a great believer (Heb 11:31) and as one whose faith proved itself by good works, Jam 2:25.

2:15 Because Rahab’s house stood on the town wall, she could hide the men on the flat roof of her house (2:6) and let them out through the window, down the outer side of the wall.
