The Israelites have fallen into unfaithfulness to God and have been conquered by the Philistines.
The Israelites cried out to God to send someone to help them.
God sent Samson, the strongest man alive, to help fight against the Philistines.
My hair gives me strength!
Samson killed a lion bare handed, set 300 foxes afire in the Philistine's fields, and killed a thousand Philistines with the bone of a donkey.
He'll never know...
Samson fell in love with Delilah, who was bribed by the Philistines, and told her the secret of his strength which was his long hair. Delilah secretly cuts his hair so all of his strength leaves him and he is captured.
Samson's hair grew back, and so when the Philistines taunt him in the temple of their chief god, Samson stands between pillars and pushes them, killing himself and numerous amount of Philistines.
