Upon the town wall - The town wall probably formed the back wall of the house, and the window opened therefore into the country. (Compare Paul's escape, 2 Corinthians 11:33).

Then she let them down by a cord etc. - The natural place of this verse is after the first clause of Joshua 2:21; for it is certain that she did not let them down in the basket till all those circumstances marked from Joshua 2:16-20 inclusive had taken place.

She dwelt upon the wall - That is, either the wall of the city made a part of her house or her house was built close to the wall, so that the top or battlements of it were above the wall with a window that looked out to the country. As the city gates were now shut there was no way for the spies to escape but through this window; and in order to this she let them down through the window in a basket suspended by a cord, till they reached the ground on the outside of the wall.

Then she let them down by a cord through the window,.... Which must be large, and the cord strong, as well as she herself a masculine woman, to let down two men by it, unless she employed any of her servants in the affair; though this being so great a secrecy, it is probable she trusted none of her domestics with it as little as possible: in like manner the Apostle Paul was let down by the wall of Damascus in a basket, Acts 9:25; Jarchi supposes it was the same cord and window, by means of and in at which her gallants used to come and go:

for her house was upon the town wall; in a suitable and convenient place to receive her guests and gallants: and it is observed, that harlots have had their houses on or under walls: Martial speaks of harlots whom he calls (l) Summoenianae, whores that plied under the walls and in the suburbs of cities:

and she dwelt upon the wall; that part of the house in which she particularly dwelt was built on or over the wall, and the rest towards the city was for the entertainment of persons that resorted to her house.

(l) Epigram. l. 3. Ep. 62.

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.

Then she let them down by a cord through the window: for her house was upon the town wall, and she dwelt upon the wall.

2:15 Town - wall - Which gave her the opportunity of dismissing them when the gates were shut. Upon the wall - Her particular dwelling was there: which may possibly be added, because the other part of her house was reserved for the entertainment of strangers.

15. her house was upon the town wall-In many Oriental cities houses are built on the walls with overhanging windows; in others the town wall forms the back wall of the house, so that the window opens into the country. Rahab's was probably of this latter description, and the cord or rope sufficiently strong to bear the weight of a man.

2:8-21 Rahab had heard of the miracles the Lord wrought for Israel. She believed that his promises would certainly be fulfilled, and his threatenings take effect; and that there was no way of escape but by submitting to him, and joining with his people. The conduct of Rahab proved that she had the real principle of Divine faith. Observe the promises the spies made to her. The goodness of God is often expressed by his kindness and truth, Ps 117:2; in both these we must be followers of him. Those who will be conscientious in keeping promises, are cautious in making them. The spies make needful conditions. The scarlet cord, like the blood upon the doorpost at the passover, recalls to remembrance the sinner's security under the atoning blood of Christ; and that we are to flee thereto for refuge from the wrath of a justly offended God. The same cord Rahab used for the saving of these Israelites, was to be used for her own safety. What we serve and honour God with, we may expect he will bless, and make useful to us.
