Thus far, in our description of Joshua’s conquest, we have seen how his good generalship secured possession of the hills--the central hills only, and not the plains. The Canaanites still dwelt in the plains round about. The Philistines held the south-west. The Phœnicians were secure in the north. The outlying nations of Edom and Moab were undisturbed. In this condition things remained for a long time; and the Israelites, occupying the hills only, were not likely to become a race of sailors. Nor did they desire it, if we may judge from such notices of the sea as occur in the Bible, for they seem to show the awe with which the writers regarded its rolling waves. And besides, the coast was not suited for it. The principal harbour was Tyre; but that was in Phœnicia, which was hardly to be included in Palestine. South of Tyre we have Accho, Caipha, and Joppa; but these are by no means good and convenient as ports. Accho is the best, but has been the least used, although Napoleon considered it “the key of Palestine.” It was to Joppa that the Phœnicians brought timber in rafts for the building of Solomon’s Temple; and thence it was carried by road to Jerusalem. It was at Joppa that Jonah found a ship going to Tarshish, and took his passage. If the sea coast was little available for the Israelites, the Jordan was still worse: a narrow, shallow, rocky stream, ending in the Dead Sea, it led to nowhere, and was useless for purposes of commerce. Naturally the capitals of the country were inland--Jerusalem in the centre of the hills, and afterwards Shechem. The main road of the country ran from south to north, along the watershed, the backbone of highest ground. But since the hills were comparatively unfruitful, the dwellers there suffered more in times of famine than the dwellers in the plains. In times of war they had some advantage, and preferred to fight from the hillsides, as they did not possess chariots and horses, and could have found no use for them. Their enemies said of them,--“their God is a God of the hills; He is not a God of the plains!”
