accursed: or, devoted

Geneva Study Bible

And the city shall be {l} accursed, even it, and all that are therein, to the LORD: only Rahab the harlot shall live, she and all that are with her in the house, because she hid the messengers that we sent.

(l) That is appointed wholly to be destroyed.Joshua 6:17 Parallel Commentaries

Jericho Itself.
We read, that this city was not only wasted by Joshua with fire and sword, but cursed also. "Cursed be he before the Lord, who shall rise up and build that city Jericho," Joshua 6:26. "Nor was another city to be built (says the Talmudists), which was to be called by the name of Jericho: nor was Jericho itself to be built, although to be called by another name." And yet I know not by what chance this city crept out of dust and rubbish, lived again, and flourished, and became the second city to Jerusalem. …

Joshua
The book of Joshua is the natural complement of the Pentateuch. Moses is dead, but the people are on the verge of the promised land, and the story of early Israel would be incomplete, did it not record the conquest of that land and her establishment upon it. The divine purpose moves restlessly on, until it is accomplished; so "after the death of Moses, Jehovah spake to Joshua," i. 1. The book falls naturally into three divisions: (a) the conquest of Canaan (i.-xii.), (b) the settlement of the …
