Samson's strength in the Bible, as described in the Book of Judges (chapters 13-16), is portrayed as a divine gift from God, tied to his Nazarite vow. This vow included not cutting his hair, avoiding alcohol, and refraining from touching anything unclean.

His strength was not merely physical but spiritual, directly linked to his faithfulness to the Nazarite vow, particularly the uncut hair. When Delilah betrayed him by cutting his hair, he lost his strength (Judges 16:17-20), only regaining it when his hair began to grow back and he sought God’s power. The narrative emphasizes that his abilities were not his own but came from God’s Spirit, used to deliver Israel from the Philistines.
