In another way Elijah conveyed the lesson of the great value residing in devotion to the study of the Torah. Disguised as a Rabbi, he was approached by a man who promised to relieve him of all material cares if he would but abide with him. Refusing to leave Jabneh, the centre of Jewish scholarship, he said to the tempter: "Wert thou to offer me a thousand million gold denarii, I would not quit the abode of the law, and dwell in a place in which there is no Torah."
By Torah, of course, is meant the law as conceived and interpreted by the sages and the scholars, for Elijah was particularly solicitous to establish the authority of the oral law, as he was solicitous to demonstrate the truth of Scriptural promises that appeared incredible at first sight. For instance, he once fulfilled Rabbi Joshua ben Levi's wish to see the precious stones which would take the place of the sun in illuminating Jerusalem in the Messianic time. A vessel in mid-ocean was nigh unto shipwreck. Among a large number of heathen passengers there was a single Jewish youth. To him Elijah appeared and said, he would rescue the vessel, provided the boy went to Rabbi Joshua ben Levi, and took him to a certain place far removed from the town and from human habitation, and showed him the gems. The boy doubted that so great a man would consent to follow a mere slip of a youth to a remote spot, but, reassured by Elijah, who told him of Rabbi Joshua's extraordinary modesty, he undertook the commission, and the vessel with its human freight was saved. The boy came to the Rabbi, besought him to go whither he would lead, and Joshua, who was really possessed of great modesty, followed the boy three miles without even inquiring the purpose of the expedition. When they finally reached the cave, the boy said: "See, here are the precious stones!" The Rabbi grasped them, and a flood of light spread as far as Lydda, the residence of Rabbi Joshua. Startled, he cast the precious stones away from him, and they disappeared.
