Israelite hero portrayed in an epic narrative in the Old Testament (Judg. 13–16). He was a Nazirite (q.v.) and a legendary warrior whose incredible exploits hint at the weight of Philistine pressure on Israel during much of the early, tribal period of Israel in Canaan (1200–1000). The Book of Judges ranks him with other divinely inspired warriors who delivered the community to establish themselves as its judges.

The Old Testament narrative, only alluding to Samson's “twenty years” activity as a judge, presents a few episodes, principally concerned with the beginning and the end of his activity. Before his birth his parents, peasants of the tribe of Dan at Zorah, near Jerusalem, learned through a theophany (manifestation of a divinity) that he was to be dedicated to the life of a Nazirite; (Nazirite) i.e., one set aside for God by a vow to abstain from strong drink, from shaving or cutting the hair, and from contact with a dead body.

Samson possessed extraordinary physical strength, and the moral of his saga relates the disastrous loss of his power to the violation of his Nazirite vow. Credited with remarkable exploits—e.g., the slaying of a lion and moving the gates of Gaza—he first broke his religious promises by feasting with a woman from the neighbouring town of Timnah, who was also a Philistine, one of Israel's mortal enemies. Other remarkable deeds follow; e.g., his decimating the Philistines in a private war. On another occasion he repulsed their assault on him at Gaza, where he had gone to visit a harlot. He finally fell victim to his foes through love of Delilah, a woman of the valley of Sorek, who beguiled him into revealing the secret of his strength: his long Nazirite hair. As he slept, Delilah had his hair cut and betrayed him. He was captured, blinded, and enslaved by the Philistines, but in the end he was granted his revenge; through the return of his old strength, he demolished the great Philistine temple of the god Dagon, at Gaza, destroying his captors and himself (Judg.16:4–30).

With his life revolving around his relations with Philistine women, Samson is depicted in the Book of Judges as being ruled by passion, which, although the cause of his downfall, nevertheless provided the means (in his frenzied force) with which he struggled for the vindication of Israel's God, Yahweh. His death in the temple is presented not as suicidal but, according to the general interpretation of biblical scholars, as a return to the original mission (as “judge” and Nazirite) that he had temporarily abandoned.

The cycle of the Samson stories is regarded by most liberal critics, and even by some Jewish interpreters in the Talmudic period (from the 1st century AD), as legendary or epical. More conservative exegetes, while admitting the unlikeliness of the events and the folkloristic style of the text, nevertheless claim to identify a core of historical truth in the saga, albeit embellished by popular imagination and augmented in rabbinical literature. Samson, accordingly, was taken by the editor of Judges as illustrating his general thesis—that, when the Israelites were unfaithful to Yahweh, they were oppressed and, when they appealed to him, they were liberated.
