The king was successful in subduing the enemies of the Hebrews, and consolidated the tribes and settled the affairs of the new state. But towards the close of his reign, his reason became disturbed: fits of gloom and despondency passed into actual insanity, which clouded the closing years of his life. At last he and his three sons fell in battle with the Philistines upon Mount Gilboa (about 1055 B.C.). THE REIGN OF DAVID (about 1055-1015 B.C.).--Upon the death of Saul, David, son of Jesse, of the tribe of Judah, who had been previously anointed and encouraged to expect the crown by the prophet Samuel, assumed the sceptre. This warlike king transformed the pastoral and half-civilized tribes into a conquering people, and, in imitation of the monarchs of the Nile and the Euphrates, extended the limits of his empire in every direction, and waged wars of extermination against the troublesome tribes of Moab and Edom. Poet as well as warrior, David enriched the literature of his own nation and of the world with lyric songs that breathe such a spirit of devotion and trust that they have been ever since his day the source of comfort and inspiration to thousands. [Footnote: The authorship of the different psalms is a matter of debate, yet critics are very nearly agreed in ascribing the composition of at least a considerable number of them to David.] He had in mind to build at Jerusalem, his capital city, a magnificent temple, and spent the latter years of his life in collecting material for this purpose. In dying, he left the crown to Solomon, his youngest son, his eldest, Absalom, having been slain in a revolt against his father, and the second, Adonijah, having been excluded from the succession for a similar crime. THE REIGN OF SOLOMON (about 1015-975 B.C.).--Solomon did not possess his father's talent for military affairs, but was a liberal patron of architecture, commerce, and learning. He erected, with the utmost magnificence of adornment, the temple at Jerusalem, planned by his father David. King Hiram of Tyre, who was a close friend of the Hebrew monarch, aided him in this undertaking by supplying him with the celebrated cedar of Lebanon, and with Tyrian architects, the most skilled workmen at that time in the world. The dedication ceremonies upon the completion of the building were most imposing and impressive. Thenceforth this temple was the centre of the Jewish worship and of the national life. [Illustration: THE TEMPLE OF SOLOMON. (A Restoration.)] For the purpose of extending his commerce, Solomon built fleets upon the Mediterranean and the Red Sea. The most remote regions of Asia and Africa were visited by his ships, and their rich and wonderful products made to contribute to the wealth and glory of his kingdom.
