Elijah's promise to bestow a double portion of his wondrous spirit upon his disciple was realized instantaneously. During his life Elisha performed sixteen miracles, and eight was all his master had performed. The first of them, the crossing of the Jordan, was more remarkable than the corresponding wonder done by Elijah, for Elisha traversed the river alone, and Elijah had been accompanied by Elisha. Two saints always have more power than one by himself.
His second miracle, the "healing" of the waters of Jericho, so that they became fit to drink, resulted in harm to himself, for the people who had earned their livelihood by the sale of wholesome water were very much incensed against the prophet for having spoiled their trade. Elisha, whose prophetic powers enabled him to read both the past and the future of these tradesmen, knew that they, their ancestors, and their posterity had "not even the aroma of good about them." Therefore he cursed them. Suddenly a forest sprang up and the bears that infested it devoured the murmuring traders. The wicked fellows were not undeserving of the punishment they received, yet Elisha was made to undergo a very serious sickness, by way of correction for having yielded to passion. In this he resembled his master Elijah; he allowed wrath and zeal to gain the mastery over him. God desired that the two great prophets might be purged of this fault. Accordingly, when Elisha rebuked King Jehoram of Israel, the spirit of prophecy forsook him, and he had to resort to artificial means to re-awaken it within himself.
