The treatment of a defeated enemy among the Jews rested upon a similar religious foundation. In the East, we find a special cruelty in the conduct of war. The wars of the Jews and Assyrians were wars of extermination. The whole of the _Old Testament_, it has been said, resounds with the clash of arms.[9] “An eye for an eye, a tooth for a tooth!” was the command of Jehovah to his chosen people. Vengeance was bound up in their very idea of the Creator. The Jews, unlike the followers of Mahomet, attempted, and were commanded to attempt no violent conversion[10]; they were then too weak a nation; but they fought, and fought with success against the heathen of neighbouring lands, the Lord of Hosts leading them forth to battle. The God of Israel stood to his chosen people in a unique and peculiarly logical relation. He had made a covenant with them; and, in return for their obedience and allegiance, cared for their interests and advanced their national prosperity. The blood of this elect people could not be suffered to intermix with that of idolaters. Canaan must be cleared of the heathen, on the coming of the children of Israel to their promised land; and mercy to the conquered enemy, even to women, children or animals was held by the Hebrew prophets to be treachery to Jehovah. (_Sam._ XV.; _Josh._ VI. 21.) [9] “The Lord is a man of war,” said Moses (_Exodus_ XV. 3). Cf. _Psalms_ XXIV. 8. He is “mighty in battle.” [10] This was bound up with the very essence of Islam; the devout Mussulman could suffer the existence of no unbeliever. Tolerance or indifference was an attitude which his faith made impossible. “When ye encounter the unbelievers,” quoth the prophet (_Koran_, ch. 47), “strike off their heads, until ye have made a great slaughter among them.... Verily if God pleased he could take vengeance on them without your assistance; but he commandeth you to fight his battles.” The propagation of the faith by the sword was not only commanded by the Mohammedan religion: it was that religion itself.
