This king was Azariah ("My strength is Jehovah"), the son of Amaziah. He is called Uzziah by the Chronicler, and in some verses of the brief references to his long reign in the Book of Kings. It is not certain that he was the eldest son of Amaziah;[342] but he was so distinctly the ablest, that, at the age of sixteen, he was chosen king by "all the people." His official title to the world must have been Azariah, for in that form his name occurs in the Assyrian records. Uzziah seems to have been the more familiar title which he bore among his people.[343] There seems to be an allusion to both names--Jehovah-his-helper, and Jehovah-his-strength--in the Chronicles: "God _helped him_, and made him to prosper; and his name spread far abroad, and he was marvellously helped, _till he was strong_." The Book of Kings only devotes a few verses to him; but from the Chronicler we learn much more about his prosperous activity. His first achievement was to recover and fortify the port of Elath, on the Red Sea,[344] and to reduce the Edomites to the position they had held in the earlier days of his father's reign. This gave security to his commerce, and at once "his name spread far abroad, even to the entering in of Egypt." He next subdued the Philistines; took Gath, Jabneh, and Ashdod; dismantled their fortifications, filled them with Hebrew colonists, and "smote all Palestine with a rod."[345] He then chastised the roving Arabs of the Negeb or south country in Gur-Baal and Maon, and suppressed their plundering incursions. His next achievement was to reduce the Ammonite Emîrs to the position of tributaries, and to enforce from them rights of pasturage for his large flocks, not only in the low country (_shephelah_), but in the southern wilderness (_midbar_), and in the _carmels_ or fertile grounds among the Trans-Jordanic hills. Having thus subdued his enemies on all sides, he turned his attention to home affairs--built towers, strengthened the walls of Jerusalem at its most assailable points, provided catapults and other instruments of war, and rendered a permanent benefit to Jerusalem by irrigation and the storing of rain-water in tanks. All these improvements so greatly increased his wealth and importance that he was able to renew David's old force of heroes (Gibborim), and to increase their number from six hundred to two thousand six hundred, whom he carefully enrolled, equipped with armour, and trained in the use of engines of war. And he not only extended his boundaries southwards and eastwards, but appears to have been strong enough, after the death of Jeroboam II., to make an expedition northwards, and to have headed a Syrian coalition against Tiglath-Pileser III., in B.C. 738. He is mentioned in two notable fragments of the annals of the eighth year of this Assyrian king. He is there called Azrijahu, and both his forces and those of Hamath seem to have suffered a defeat.[346]
