Delilah then said to Samson, "Until now, 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
and tightened it with the pin. Again she called to him, "Samson, the Philistines are upon you!"1 He awoke from his sleep and pulled up the pin and the loom, with the fabric.
