Judges 16:12-13

¹²So Delilah took new thick cords, knotting them tightly round him, and said to him, The Philistines are on you, Samson. And men were waiting secretly in the inner room. And the cords were broken off his arms like threads.

¹³Then Delilah said to Samson, Up to now you have made sport of me with false words; now say truly, how may you be put in bands? And he said to her, If you get the seven twists of my hair worked into the cloth you are making and fixed with the pin, I will become feeble and will be like any other man.
