Samuel narrates the most consequential transition in the Hebrew Bible's political history, from the loose tribal confederacy of the judges to a centralized monarchy, told through the intertwined lives of three men: Samuel, the last judge and a prophet who anoints Israel's first two kings; Saul, chosen and then rejected as king after repeated disobedience; and David, the shepherd anointed in secret who rises through Saul's court, exile, and eventual succession to found the dynasty the rest of the Hebrew Bible treats as normative.
The book gives its fullest and most psychologically detailed portrait of any figure in the Hebrew Bible to David, tracing his triumph over Goliath, his complicated friendship with Saul's son Jonathan, his years as a fugitive, his eventual kingship, and, in its second half, a long, morally unflinching account of his own family's unraveling after his affair with Bathsheba and the murder of her husband Uriah, a section scholars call the Succession Narrative for its focus on which of David's sons will inherit the throne. God's ambivalence toward the monarchy itself runs through the book from Samuel's warning about what a king will take from the people, in chapter 8, onward, a genuine internal tension the text never fully resolves even as it commits fully to David's line.
