This tribe of shepherds was known as the Hebrews or, as we call them, the Jews. They had wandered far and wide, and after many years of dreary peregrinations they had been given shelter in Egypt. For more than five centuries they had dwelt among the Egyptians and when their adopted country had been overrun by the Hyksos marauders (as I told you in the story of Egypt) they had managed to make themselves useful to the foreign invader and had been left in the undisturbed possession of their grazing fields. But after a long war of independence the Egyptians had driven the Hyksos out of the valley of the Nile and then the Jews had come upon evil times for they had been degraded to the rank of common slaves and they had been forced to work on the royal roads and on the Pyramids. And as the frontiers were guarded by the Egyptian soldiers it had been impossible for the Jews to escape. After many years of suffering they were saved from their miserable fate by a young Jew, called Moses, who for a long time had dwelt in the desert and there had learned to appreciate the simple virtues of his earliest ancestors, who had kept away from cities and city-life and had refused to let themselves be corrupted by the ease and the luxury of a foreign civilisation. Moses decided to bring his people back to a love of the ways of the patriarchs. He succeeded in evading the Egyptian troops that were sent after him and led his fellow tribesmen into the heart of the plain at the foot of Mount Sinai. During his long and lonely life in the desert, he had learned to revere the strength of the great God of the Thunder and the Storm, who ruled the high heavens and upon whom the shepherds depended for life and light and breath. This God, one of the many divinities who were widely worshipped in western Asia, was called Jehovah, and through the teaching of Moses, he became the sole Master of the Hebrew race. One day, Moses disappeared from the camp of the Jews. It was whispered that he had gone away carrying two tablets of rough-hewn stone. That afternoon, the top of the mountain was lost to sight. The darkness of a terrible storm hid it from the eye of man. But when Moses returned, behold! there stood engraved upon the tablets the words which Jehovah had spoken unto the people of Israel amidst the crash of his thunder and the blinding flashes of his lightning. And from that moment, Jehovah was recognised by all the Jews as the Highest Master of their Fate, the only True God, who had taught them how to live holy lives when he bade them to follow the wise lessons of his Ten Commandments.
