Judges 16:4-5, 19-20

Afterward it happened that he 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.”

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. And she said, “The Philistines are upon you, Samson!” So he awoke from his sleep, and said, “I will go out as before, at other times, and shake myself free!” But he did not know that the LORD had departed from him.
