Samson
In the Hebrew Bible, Samson (; , "", "man of the sun") was the last of the judges of the ancient Israelites mentioned in the Book of Judges (chapters 13 to 16) and one of the last leaders who "judged" Israel before the institution of the monarchy. He is sometimes considered to be an Israelite version of the popular Near Eastern folk hero also embodied by the Sumerian Enkidu and the Greek Heracles.

The biblical account states that Samson was a Nazirite, and that he was given immense strength to aid him against his enemies and allow him to perform superhuman feats, including slaying a lion with his bare hands and massacring an entire army of Philistines using only the jawbone of a donkey.

Samson [SEP] Introduction
However, if Samson's long hair were cut, then his Nazirite vow would be violated and he would lose his strength. Samson was betrayed by his lover Delilah, who, sent by the Philistines officials to entice him, ordered a servant to cut his hair while he was sleeping and turned him over to his Philistine enemies, who gouged out his eyes and forced him to grind grain in a mill at Gaza. While there, his hair began to regrow. When the Philistines took Samson into their temple of Dagon, Samson asked to rest against one of the support pillars. After being granted permission, he prayed to God and miraculously recovered his strength, allowing him to bring down the columns, collapsing the temple and killing himself as well as all of the Philistines.
