But however vigorously they may have plied the occupation of Corsairs at the outset of their career, there was, it would appear, a rapid falling off in their maritime prowess; it was on land, and as soldiers, that they displayed their bravery and gained their fame. Their geographical position, indeed, on the direct and almost only route for caravans passing between Asia and Africa, must have contributed to their success. The number of such caravans was considerable, for although Egypt had ceased to be a conquering nation on account of her feebleness at home, she was still one of the great centres of production, and the most important market of the East. A very great part of her trade with foreign countries was carried on through the mouths of the Nile, and of this commerce the Phoenicians had made themselves masters; the remainder followed the land-routes, and passed continually through the territory of the Philistines. These people were in possession of the tract of land which lay between the Mediterranean and the beginning of the southern desert, forming as it were a narrow passage, into which all the roads leading from the Nile to the Euphrates necessarily converged. The chief of these routes was that which crossed Mount Carmel, near Megiddo, and passed up the valleys of the Litâny and the Orontes. This was met at intervals by other secondary roads, such as that which came from Damascus by way of Tabor and the plain of Jezreel, or those which, starting out from the highland of Gilead, led through the fords of the Lower Jordan to Ekron and Gath respectively. The Philistines charged themselves, after the example and at the instigation of the Egyptians, with the maintenance of the great trunk road which was in their hands, and also with securing safe transit along it, as far as they could post their troops, for those who confided themselves to their care. In exchange for these good offices they exacted the same tolls which had been levied by the Canaanites before them. In their efforts to put down brigandage, they had been brought into contact with some of the Hebrew clans after the latter had taken possession of Canaan. Judah, in its home among the mountains of the Dead Sea, had become acquainted with the diverse races which were found there, and consequently there had been frequent intermarriages between the Hebrews and these peoples. Some critics have argued from this that the chronicler had this fact in his mind when he assigned a Canaanite wife, Shuah, to the father of the tribe himself. He relates how Judah, having separated from his brethren, “turned in to a certain Adullamite, whose name was Hiram,” and that here he became acquainted with Shuah, by whom he had three sons. With Tamar, the widow of the eldest of the latter, he had accidental intercourse, and two children, Perez and Zerah, the ancestors of numerous families, were born of that union.* * Gen. xxxviii., where there is a detailed account of Judah’s unions.
