The book falls naturally into three divisions: (_a_) the conquest of Canaan (i.-xii.), (_b_) the settlement of the land (xiii.-xxii.), (_c_) the last words and death of Joshua (xxiii., xxiv.). This period seems to be better known than that of the wilderness wanderings, and, especially throughout the first twelve chapters, the story moves forward with a firm tread. On the death of Moses, Joshua assumes the leadership, and makes preparations for the advance (i.). After sending men to Jericho to spy and report upon the land (ii.), the people solemnly cross the Jordan, preceded by the ark (iii.); and, to commemorate the miracle by which their passage had been facilitated, memorial stones are set up (iv.). After circumcision had been imposed, v. 1-9, the passover celebrated, v. 10-12, and Joshua strengthened by a vision, v. 13-15, the people assault and capture Jericho (vi.). This initial success was followed by a sharp and unexpected disaster at Ai, for which Achan, by his violation of the law of the ban, was held guilty and punished with death (vii.). A renewed assault upon Ai was this time successful.[1] (viii.). Fear of Israel induced the powerful Gibeonite clan to make a league with the conquerors (ix.). Success continued to remain with Israel, so that south (x.) and north, xi. 1-15, the arms of Israel were victorious, xi. 16-xii. [Footnote 1: The book of Joshua describes only the southern and northern campaigns; it gives no details concerning the conquest of Central Palestine. This omission is apparently due to the Deuterouomic redactor, who, in place of the account itself, gives a brief idealization of its results in viii. 30-35.] Much of the land remained still unconquered, but arrangements were made for its ideal distribution. The two and a half tribes had already received their inheritance east of the Jordan, and the rest of the land was allotted on the west to the remaining tribes. Judah's boundaries and cities are first and most exhaustively given; then come Manasseh and Ephraim, with meagre records, followed by Benjamin, which again is exhaustive, then by Simeon, Zebulon, Issachar, Asher, Naphtali and Dan (xiii.-xix.). Three cities on either side of Jordan were then set apart as cities of refuge for innocent homicides, and for the Levites forty-eight cities with their pasture land, xx. 1-xxi. 42. As Israel was now in possession of the land in accordance with the divine promise, xxi. 43-45, Joshua dismissed the two and a half tribes to their eastern home with commendation and exhortation, xxii. 1-8. Incurring the severe displeasure of the other tribes by building what was supposed to be a schismatic altar, they explained that it was intended only as a memorial and as a witness of their kinship with Israel, xxii. 9-34.
