David is a descendent of Judah son of Jacob. He was the most worshippful of all people. His voice and appearance were handsome. The Israelites loved David and wanted him to be king over them. Saul ordered this to be so, giving the kingship to him. God united in David both kingship and prophethood, the best of this world and the next. Before him kingship had been vested in one tribe and prophethood in another, but they were brought together in David. Historians report that he lived 100 years, that the length of his reign was 40 years, and that he had twelve sons.
