First Samuel opens at one of the great hinges of Israel's history: the nation moves from the chaotic days of the judges, when "everyone did what was right in his own eyes," into the age of kings. Through the lives of three central figures—Samuel the prophet, Saul the rejected king, and David the king after God's own heart—the book asks who is fit to rule God's people, and answers that true kingship belongs to the Lord and to the king he chooses.
Author, Date, and Audience
The book is named for Samuel, the prophet who anoints Israel's first two kings, but it does not name its author and clearly records events after Samuel's death (1 Samuel 25:1). Jewish tradition (the Talmud) credits Samuel with the early chapters, with Nathan and Gad completing the work (compare 1 Chronicles 29:29). Most likely an inspired compiler drew together earlier prophetic records sometime after the kingdom divided, since the narrative distinguishes "Israel" from "Judah" (1 Samuel 11:8; 27:6). In the Hebrew canon, 1 and 2 Samuel form a single book; they were divided in the Greek Septuagint. Whatever the precise date of final composition, the events themselves belong to roughly the eleventh century B.C., and the book addresses a covenant people wrestling with what it means to be ruled rightly under God.
Purpose and Major Themes
Written to a people who had demanded a king "like all the nations" (1 Samuel 8:5), the book explains how kingship came to Israel and what God requires of those who hold authority. Several themes weave through it. First, the sovereignty of God: he raises up the lowly and brings down the proud, a truth sung in Hannah's prayer (2:1-10) and displayed as a barren woman's son becomes a prophet and a shepherd boy becomes king. Second, the priority of obedience over outward religion—"to obey is better than sacrifice" (15:22)—seen in the contrast between Saul, who looks the part but will not submit, and David, a man after God's own heart. Third, God looks on the heart, not on appearances (16:7). Running beneath it all is God's covenant faithfulness, which carries his people forward despite their failures.
Structure
The narrative unfolds in three overlapping movements: the rise of Samuel and the decline of the priesthood under Eli (chapters 1-7); the reign and rejection of Saul, Israel's first king (chapters 8-15); and the anointing and long testing of David as he waits for the throne while Saul pursues him (chapters 16-31). The book ends in shadow, with Saul's death on Mount Gilboa, leaving David poised but not yet enthroned—an unresolved tension that 2 Samuel will take up.
Christ in 1 Samuel
First Samuel quietly prepares the way for the gospel. Hannah's song that the Lord "will give strength to his king and exalt the horn of his anointed" (2:10) reaches forward to a greater Anointed One—the word is Messiah, and in Greek Christ—and Mary will echo Hannah's praise in her own Magnificat (Luke 1:46-55). David, the shepherd-king from Bethlehem who is rejected and hunted before he reigns, foreshadows the Son of David, born in the same town, despised by his own, and crowned only through suffering. When David alone steps forward to face Goliath on behalf of a trembling people, we glimpse the true Champion who would conquer sin and death for those who could not save themselves. The book thus belongs to the unbroken story that runs from God's covenant with David (which 2 Samuel 7 will seal) to its fulfillment in Jesus Christ, the King whose throne is established forever.
