[389] When David had given these admonitions to his son about public affairs, and about his friends, and about those whom he knew to deserve punishment, he died, having lived seventy years, and reigned seven years and six months in Hebron over the tribe of Judah, and thirty-three years in Jerusalem over all the country. This man was of an excellent character, and was endowed with all virtues that were desirable in a king, and in one that had the preservation of so many tribes committed to him; for he was a man of valor in a very extraordinary degree, and went readily and first of all into dangers, when he was to fight for his subjects, as exciting the soldiers to action by his own labors, and fighting for them, and not by commanding them in a despotic way. He was also of very great abilities in understanding, and apprehension of present and future circumstances, when he was to manage any affairs. He was prudent and moderate, and kind to such as were under any calamities; he was righteous and humane, which are good qualities, peculiarly fit for kings; nor was he guilty of any offense in the exercise of so great an authority, but in the business of the wife of Uriah. He also left behind him greater wealth than any other king, either of the Hebrews or, of other nations, ever did.
