Judges 16:13-14

13Then Delilah said to Samson, ‘You have deceived me again as if I was a fool. Now you must tell me the truth. Tell me how someone can make you weak.’ Samson replied, ‘You see that my long hair is tied in seven tails. You must tie them into the cloth that is on the loom. Fix them there very strongly. If you do that, I will become weak, like other men.’

14Delilah did this while Samson was asleep. She took the seven tails of his hair and she tied them into the cloth on the loom. She fixed them with a strong peg. Then she shouted, ‘Samson, the Philistines are here!’ He woke up and he pulled out the peg. He tore his hair away from the cloth on the loom so that he was free.
