Jeroboam was effectually aided in his ambitious plans by Shishak (Sheshenk), who, it is said, married his wife's elder sister Ano to the fugitive Israelite, just as he had given another sister in marriage to the Idumæan prince who had taken refuge with him. Shishak probably had furnished Jeroboam with the supplies of money that enabled him to return to his fatherland, and now the new king seems to have formed an alliance with him against Judah. Thus Rehoboam was prevented from undertaking any noteworthy steps against Israel. In order to secure himself from Egyptian and Israelitish attacks, Rehoboam erected a chain of fortresses in a circuit of several miles round about the capital. But they failed him in the hour of need. Shishak, with an overwhelming force, undertook a war against Rehoboam in the fifth year of the Jewish king's reign (972). Overcome by excess of numbers, the strongholds were taken one after another by the Egyptian armies, and Shishak pressed forward as far as Jerusalem. It appears that the capital yielded without a struggle, and the Egyptian king contented himself with seizing the treasures which Solomon had deposited in the palace and the Temple. He appropriated all the money then in Jerusalem, as well as the golden shields and spears which the king's guards used in royal processions to the Temple. He, however, left the kingdom of Judah intact, did not even touch the walls of Jerusalem, and left Rehoboam on his throne. On his return, Shishak commemorated his deeds of prowess and his victories over Judah and other districts by records and monuments. The alliance between Solomon and the king of Egypt was thus of but short duration. His son learned the futility of such a treaty, and experienced how little trust can be placed in plans and political measures, though apparently the outcome of the deepest calculation and forethought. Solomon, in spite of his wisdom, had acted thoughtlessly in regard to the union with the daughter of Pharaoh. He had built her a special palace, and within a few years after his decease, an Egyptian king ransacked this very palace and other monumental buildings of Solomon, and plundered them of all their treasures. The grandeur and power of Solomon's kingdom were at an end.
