Question
Who was Samson, the strongman whose strength was in his hair?
Analysis
The strength was God's, not magic in the hair
The narrative is careful about where the strength came from. It was the Spirit of the LORD that "rushed upon him" at his mighty deeds (Judges 14:6; Judges 14:19; Judges 15:14), and when the secret was gone the text does not say the haircut drained a power in the hair, it says the LORD had left him (Judges 16:20). The hair was the sign of the Nazirite vow, the outward mark of a life consecrated to God (Numbers 6:5); cutting it broke the last piece of that consecration Samson still kept. So his strength is best read as God's gift tied to his calling, with the uncut hair as its token, not as a charm. That his strength returned as his hair grew back and he prayed (Judges 16:22; Judges 16:28) fits the same point: the power was always the LORD's to give.
The Nazirite vow
A Nazirite (Numbers 6:1–Numbers 6:8) took a vow to be set apart to God, marked by three things: no wine or product of the vine, no cutting the hair, and no contact with a dead body. Samson's was a lifelong Nazirite calling from birth (Judges 13:5; Judges 13:7), unusual because it was assigned by God rather than taken for a set time. Across his life he brushed against all three limits, feasting (Judges 14:10), touching the lion's carcass for honey (Judges 14:8; Judges 14:9), and finally the hair, so the shaving is the last and decisive break of a vow already strained.
A flawed deliverer
Samson is portrayed honestly as impulsive and self-willed, driven by anger, by riddles and revenge, and by relationships with Philistine women (Judges 14:1–Judges 14:3; Judges 16:1; Judges 16:4). He is never called a model of wisdom. Yet through him God "began to deliver Israel" from the Philistines (Judges 13:5), and Hebrews names him among those who by faith … (Hebrews 11:32; Hebrews 11:34). The book presents both the gift and the man's failures without softening either.
