Context: 1 Samuel narrates Israel's transition from the charismatic period of the judges to institutionalized monarchy. Three characters dominate the book: Samuel (last judge, first writing prophet, who bridges the two eras), Saul (the first king, tragically rejected), and David (the young anointed man who waits for God's timing).

Samuel: Son of Hannah — a barren woman whose fervent prayer is answered miraculously (chs. 1–2; echoed in Elizabeth and Mary in the NT). Samuel's nighttime call (ch. 3) establishes the prophetic pattern: God speaks to the young man "before the word of the Lord had been revealed to him." The Ark of the Covenant returns from Philistine captivity (chs. 4–7).

Saul and David: Saul is chosen at the people's request to be "like all the nations" — itself a sign of distrust in God. His rejection comes through partial disobedience to the divine command (chs. 13; 15). The contrast with David is theological: "man looks on the outward appearance, but the Lord looks on the heart" (16:7). The David and Goliath narrative (ch. 17) is a paradigm of faith facing the impossible by trusting in the Lord's name, not the weapons of the world.
