Judges 16:4-6, 15-21

And it came to pass afterward, that he loved a woman in the valley of Sorek, whose name was Delilah. And the lords of the Philistines came up unto her, and said unto her, Entice him, and see wherein his great strength lieth, and by what means we may prevail against him, that we may bind him to afflict him: and we will give thee every one of us eleven hundred pieces of silver. And Delilah said to Samson, Tell me, I pray thee, wherein thy great strength lieth, and wherewith thou mightest be bound to afflict thee.

And she said unto him, How canst thou say, I love thee, when thy heart is not with me? thou hast mocked me these three times, and hast not told me wherein thy great strength lieth. And it came to pass, when she pressed him daily with her words, and urged him, that his soul was vexed unto death. And he told her all his heart, and said unto her, There hath not come a razor upon my head; for I have been a Nazirite unto God from my mother’s womb: if I be shaven, then my strength will go from me, and I shall become weak, and be like any other man. And when Delilah saw that he had told her all his heart, she sent and called for the lords of the Philistines, saying, Come up this once, for he hath told me all his heart. Then the lords of the Philistines came up unto her, and brought the money in their hand. And she made him sleep upon her knees; and she called for a man, and shaved off the seven locks of his head; and she began to afflict him, and his strength went from him. And she said, The Philistines are upon thee, Samson. And he awoke out of his sleep, and said, I will go out as at other times, and shake myself free. But he knew not that Jehovah was departed from him. And the Philistines laid hold on him, and put out his eyes; and they brought him down to Gaza, and bound him with fetters of brass; and he did grind in the prison-house.
