Part of the blame for the destruction of Amalek falls upon his father, Eliphaz. He used to say to Amalek: "My son, dost thou indeed know who will posses this world and the future world?" Amalek paid no attention to his allusion to the future fortune of Israel, and his father urged it no more strongly upon him, although it would have been his duty to instruct his son clearly and fully. He should have said to him: "My son, Israel will posses this world as well as the future world; dig wells then for their use and build road for them, so that thou mayest be judged worthy to share in the future world." But as Amalek had not been sufficiently instructed by his father, in his wantonness he undertook to destroy the whole world. God, who tries the reins and the heart, said to him: "O thou fool, I created thee after all the seventy nations, but for thy sins thou shalt be the first to descend into hell." [149] To glorify the victory over Amalek, Moses built an altar, which God called "My Miracle," for the miracle God wrought against Amalek in the war of Israel was, as it were, a miracle for God. For so long as the Israelites dwell in sorrow, God feels with them, and a joy for Israel is a joy for God, hence, too, the miraculous victory over Israel's foe was a victory for God. [150] JETHRO "Smite a scorner, and the simple will beware." The destruction of Amalek brought Jethro to his senses. Jethro was originally in the same plot with Amalek, both having incited Pharaoh against Israel, but when he saw that Amalek lost this world and the other, he repented of his sinful ways, saying: "There is nothing left to me but to go over to the God of Israel"; [151] and although he dwelt in the greatest wealth and honor, he determined to set out for the desert, to Moses and his God. [152] Arrived at the camp of Israel, he could not enter it, for it was enveloped by a cloud that none could pierce, hence he wrote a letter to Moses and shot it off with an arrow, so that it fell into the camp. [153] The letter read: "I adjure thee, by thy two sons and by thy God, to come to meet me and receive me kindly. If thou wilt not do if for my sake, do it for thy wife's sake; and if thou wilt not do it for her sake, do it for thy sons' sake." For Jethro brought with him his daughter Zipporah, from whom Moses had been divorced, as well as her two sons, her only children, for after her separation from Moses, she had wed no other man. At first Moses was inclined to give no ear to this letter, but God said to him: "I, through whose word the world came into being, I bring men to Me and do not thrust them back. I permitted Jethro to approach Me, and did not push him from Me. So do thou, too, receive this man, who desires to betake himself under the wings of the Shekinah, let him approach, and do not repulse him." God herewith taught Moses that one should repulse with the left hand, and beckon with the right. [154]
