Delilah

"[to Samson ] Then she said to him, “How can you say, ‘I love you,’ when your heart is not with me? You have mocked me these three times, and have not told me where your great strength lies."

"Afterward it happened that he (Samson) loved a woman in the Valley of Sorek, whose name was Delilah. And the lords of the Philistines came up to her and said to her, “Entice him, and find out where his great strength lies, and by what means we may overpower him, that we may bind him to afflict him; and every one of us will give you eleven hundred pieces of silver.”"

"And it came to pass, when she pestered him daily with her words and pressed him, so that his soul was vexed to death, that he told her all his heart, and said to her, “No razor has ever come upon my head, for I have been a Nazirite to God from my mother’s womb. If I am shaven, then my strength will leave me, and I shall become weak, and be like any other man.” When Delilah saw that he had told her all his heart, she sent and called for the lords of the Philistines, saying, “Come up once more, for he has told me all his heart.” So the lords of the Philistines came up to her and brought the money in their hand. Then she lulled him to sleep on her knees, and called for a man and had him shave off the seven locks of his head. Then she began to torment him, and his strength left him."
