No sooner had he heard of Israel's departure from Egypt, then he set out against them and met them by the Red Sea. There, indeed, he could work them no ill, for Moses uttered against him the Ineffable Name; and so great was his confusion, that he was forced to retreat without having effected his object. Then, for some time, he tried lying hidden in ambush, and in this wise molesting Israel, but as length he gave up this game of hide-and-seek, and with a bold front revealed himself as the open enemy of Israel.
Not alone, however, did he himself declare war upon Israel, but he also seduced all the heathen nations to assist him in his enterprise against Israel. Although these declined to war upon Israel, fearing that they might have to fare like the Egyptians, they agreed to the following plan of Amalek. He said: "Follow my expedition. Should Israel conquer me, there will still be plenty of time for you to flee, but should success crown my attempt, join your fate to mine, in my undertaking against Israel."
So Amalek now marched from his settlement in Seir, which was no less than four hundred parasangs away from the encampment of the Jews; and although five nations, the Hittites, the Hivites, the Jebusites, the Amorites, and the Canaanites, had their dwellings between his home and the camp of the Jews, he insisted upon being the first to declare war upon Israel.
