Judges 16:4-6

4Some time later Samson fell in love with a woman named Delilah, who lived in the valley of Sorek.

5The rulers of the Philistines went to her and said, “Entice Samson to tell you what makes him so strong and how he can be overpowered and tied up securely. Then each of us will give you 1,100 pieces of silver.”

6So Delilah said to Samson, “Please tell me what makes you so strong and what it would take to tie you up securely.”
