Judges 16:5-8

The rulers of the Philistines went to her with a plan: “Trick Samson into telling you the secret of his great strength. Find out how we can subdue him. We’ll tie him up and make him helpless. Then each of us will give you eleven hundred pieces of silver.” So Delilah approached Samson and asked, “Please dear, won’t you tell me the secret of your strength and how you could be tied up and made helpless?” Samson replied, “If someone bound me with seven new bowstrings that haven’t been dried, I’ll become as weak as an ordinary man.” So the Philistine tyrants brought Delilah seven new bowstrings, and she tied Samson up with them.
