The Conquest of Canaan. The book of Joshua opens with the crossing of the Jordan by the forces of Israel and the establishment of a great headquarters' camp at Gilgal. By invading Western Palestine by the ford near Jericho instead of advancing round the S. of the Dead Sea, Joshua was able to drive a wedge between the Canaanites on the N. and those in the S. of the country, and thus to prevent a union of all the tribes against him. The first attack was made upon Jericho. This was the key to Western Palestine, for it was on the way to all the passes of importance into the interior. Jericho taken, Ai, another town on the principal road to the W., soon followed. The Gibeonites by a trick secured an alliance with the conqueror, who marched to attack the kings of the S. and defeated them in a pitched battle at Bethhoron, afterwards overrunning their country and destroying their towns. Thereafter the victorious leader turned his attention to the kings of the N. and defeated them in a great battle near the waters of Merom. After that, according to the chronicler, 'the land rested from war.' The conquest thus outlined was, however, far from complete. The enemy may have been routed but was not destroyed. The towns may have been overthrown, but many of them were probably soon re-fortified. And the complete subjugation of the enemy was accomplished slowly and with difficulty, not by a general campaign, but by individual tribes fighting for themselves and gradually extending their borders. We have illustrations of this in such accounts as that of Caleb driving out the sons of Anak from Hebron (Joshua 15:14), and that of the children of Joseph contending with difficulty against the Perizzites and the Rephaim (Joshua 17:14). The country was difficult for warfare, being mountainous, and favoured the defenders. The Israelites having no chariots could not meet their enemies in the plains (Joshua 17:16), and the valleys thus remained long in possession of the Canaanites. And in many cases the advance was slow and the success uncertain: see e.g. Joshua 17:12, and cp. Judges 1.
The inhabitants of Canaan at the time of the invasion, generally described as Canaanites, were divided into a number of petty kingdoms, and had no bond of union save hatred of the invaders. Amongst their divisions were the Amorites, Jebusites, Hivites, and suchlike; also there seem to have been here and there in the land surviving elements of an aboriginal people represented by the Rephaim and the sons of Anak. Their moral and religious condition is indicated by such passages as Deuteronomy 9:5 and Leviticus 18. It was so vicious and depraved as to render dangerous, if not indeed impossible, any association with them on the part of the Israelites. Uncompromising opposition to them was the only practical attitude for a people led by Jehovah, and holding His law. Hence arose the moral necessity for that order for their extermination, which has sometimes been a stumbling-block to the religious mind. The attempt to carry out that order had an effect for good upon the Israelites, in so far as it engaged them in a work of moral and spiritual sanitation: the failure to carry it out completely left open to them a source of weakness and danger, from which sprang many of their subsequent corruptions and defections from the pure worship of Jehovah.
The Canaanites were an agricultural people, somewhat more advanced than the Israelites in the arts of civilisation. The conquest of them, accordingly, meant for Israel a certain material progress, and an entry into conditions which constituted in many ways an ideal nursery of religion. They passed from a nomadic and pastoral state to the more complex stage of a settled, agricultural condition, with possibilities of village and city life. The division of the conquered territory and the settlement of the Israelite tribes upon it occupy Joshua 13-21 of the book of Joshua, which have consequently been called the 'Domesday Book of the Old Testament.'
