Judges 16:4-6

4 It came to pass afterward, that he loved a woman in the valley of Sorek, whose name was Delilah.  5 The lords of the Philistines came up to her, and said to her, Entice him, and see in which his great strength lies, and by what means we may prevail against him, that we may bind him to afflict him: and we will each give you of us eleven hundred pieces of silver.  6 Delilah said to Samson, Tell me, Please, in which your great strength lies, and with which you might be bound to afflict you.
