Judges 16:4-5, 19-20

After this it came about that he loved a woman in the valley of Sorek, whose name was Delilah. The lords of the Philistines came up to her and said to her, “Entice him, and see where his great strength lies and how we may overpower him that we may bind him to afflict him. Then we will each give you eleven hundred pieces of silver.”

She made him sleep on her knees, and called for a man and had him shave off the seven locks of his hair. Then she began to afflict him, and his strength left him. She said, “The Philistines are upon you, Samson!” And he awoke from his sleep and said, “I will go out as at other times and shake myself free.” But he did not know that the LORD had departed from him.
