Judges 16:13; Judges 16:19

13 Delilah then said to Samson, “All this time you have been making a fool of me and lying to me. Tell me how you can be tied.” He replied, “If you weave the seven braids of my head into the fabric on the loom and tighten it with the pin, I’ll become as weak as any other man.” So while he was sleeping, Delilah took the seven braids of his head, wove them into the fabric

19 After putting him to sleep on her lap, she called for someone to shave off the seven braids of his hair, and so began to subdue him. And his strength left him.
