Samson was not the creation of Cecil B. De Mille. He was a real character from the Bible, the first Nazarite mentioned in scripture and the last of the judges.
The first recorded event of Samson's life was his marriage with a Philistine woman of Timnath. He had gone there to visit and had met a young girl he fancied. He returned and told his father he wanted to marry her. Though such a marriage was not fobidden by the law of Moses as the Philistines did not form one of the seven cursed Canaanite nations, it wasn't exactly encouraged. Samson's parents tried to dissuade him, but ultimately set out to Timnath to get the girl. On the way they encountered a lion.
Samson went down to Timnah together with his father and mother. As they approached the vineyards of Timnah, suddenly a young lion came roaring toward him. The Spirit of the LORD came upon him in power so that he tore the lion apart with his bare hands as he might have torn a young goat. But he told neither his father nor his mother what he had done. (Judges 14:5-6)
The marriage took place but it was not blessed. His wife was soon taken from him and given to a friend who had attended him at his wedding. In retaliation, he caught three hundred foxes, set their tails on fire and let them loose in the fields. The Philistines in turn, burnt his wife and her father alive. A furious Samson went amok among the Philistines, "slaughtering" many of them.
A while later, three thousand men from Judah handed Samson over to the Philistines, bound with ropes.
As he approached Lehi, the Philistines came toward him shouting. The Spirit of the LORD came upon him in power. The ropes on his arms became like charred flax, and the bindings dropped from his hands. Finding a fresh jawbone of a donkey, he grabbed it and struck down a thousand men.
Some time later, he fell in love with a woman in the Valley of Sorek whose name was Delilah. The rulers of the Philistines went to her and bribed her to betray him, by ascertaining the secret behind his immense strength. After several failed attempts, Samson revealed that the secret lay in his hair. While he slept, Delilah got a man to shave off his hair. Samson was taken prisoner. He was blinded and set to the grinding wheel in prison.
Not very long later, the rulers of the Philistines assembled to offer a sacrifice to Dagon, their god, and thought that Samson could be a source of entertainment, not realizing that his hair had grown back. They had him brought in and perform for them. When the performance was over Samson asked to be shown a pillar so he could rest against it.
Then Samson reached toward the two central pillars on which the temple stood. Bracing himself against them, his right hand on the one and his left hand on the other, Samson said, "Let me die with the Philistines!" Then he pushed with all his might, and down came the temple on the rulers and all the people in it. Thus he killed many more when he died than while he lived. (Judges 16:29-30)
Samson was buried in the tomb of Manoah his father. He had led Israel twenty years.
