Judges 16:7-9

7Samson replied, ‘Someone would have to use seven new strings for bows. The strings must not have become dry. If they use those strings to tie me up, I will become weak, like other men.’

8So the Philistine rulers gave Delilah seven new strings for bows. She used them to tie Samson up while he was asleep.

9Some Philistine men hid in a room of her house. Then she shouted, ‘Samson, the Philistines are here!’ But he broke the seven strings very easily. They were like thin cotton that a fire burns. So they did not discover the secret about his strength.
