Judges 16:8 CEV

[8] The Philistine rulers gave seven new bowstrings to Delilah. They also told some of their soldiers to go to Delilah's house and hide in the room where Samson and Delilah were. If the bowstrings made Samson weak, they would be able to capture him. Delilah tied up Samson with the bowstrings and shouted, "Samson, the Philistines are attacking!" Samson snapped the bowstrings, as though they were pieces of scorched string. The Philistines had not found out why Samson was so strong.
