According to the Book of Judges, Samson is betrayed by Delilah.
The temptress Delilah cuts his Nazir–ite hair, thereby eviscerating his strength. Samson is then enslaved by his mortal enemies, the Philistines. They bind, shackle, and torment him to a temple column during their pagan rites at the Temple of Dagon. Samson thereupon brings down the colossal temple roof upon the 3,000 assembled Philistines, their rulers and priests and upon himself.
Note: This will later become known as “the Samson Defense” (meaning taking your enemies down with you).
