In order to save his kingdom from attack Solomon expended vast sums on the fortification of frontier towns. In the north he fortified Hazor; in the north-west Megiddo. The passes to Jerusalem on the west were rendered safe by the fortresses at Upper and Nether Bethhoron. The southern districts were overawed by the building of Baalath and Tamar, "the palm-city," which is described as "in the wilderness in the land,"--perhaps in the desolate tract on the road from Hebron to Elath.[196] Movers thinks that Hazezon-Tamar or Engedi is meant, as this town is called Tamar in Ezek. xlvii. 19. As the king grew more and more in power he gave full reins to his innate love of magnificence. We can best estimate the sudden leap of the kingdom into luxurious civilisation if we contrast the royalty of Saul with that of Solomon. Saul was little more than a peasant-prince, a local emîr, and such state as he had was of the humblest description. But Solomon vied with the gorgeous secular dynasts of historic empires. His position had become much more splendid owing to his alliance with the King of Egypt--an alliance of which his humbler predecessors would scarcely have dreamed. We are not told the name of his Egyptian bride, but she must have been the daughter of one of the last kings of the twenty-first Tanite dynasty--either Psinaces, or Psusennes II.[197] The dynasty had been founded at Tanis (Zoan) about B.C. 1100 by an ambitious priest named Hir-hor. It only lasted for five generations. Whatever other dower Solomon received with this Egyptian princess, his father-in-law rendered him one signal service. He advanced from Egypt with an army against the Canaanite town of Gezer, which he conquered and destroyed.[198] Solomon rebuilt it as an outpost of defence for Jerusalem. Further than this the Egyptian alliance did not prove to be of much use. The last king of this weak twenty-first dynasty was succeeded B.C. 990 by the founder of a new Bubastite dynasty, the great Shishak I. (Shesonk, Σεσόνχωσις), the protector of Jeroboam and the plunderer of Jerusalem and its Temple. Ker'amat, niece of the last king of the dynasty, married Shishak, the founder of the new dynasty, and was the mother of U-Sark-on I. (Zerah the Ethiopian).
