'Hair' in the Bible

Look, you will conceive and have a son. You must never cut his hair, for the child will be dedicated to God from birth. He will begin to deliver Israel from the power of the Philistines."

Delilah said to Samson, "Up to now you have deceived me and told me lies. Tell me how you can be subdued." He said to her, "If you weave the seven braids of my hair into the fabric on the loom and secure it with the pin, I will become weak and be like any other man."

So she made him go to sleep, wove the seven braids of his hair into the fabric on the loom, fastened it with the pin, and said to him, "The Philistines are here, Samson!" He woke up and tore away the pin of the loom and the fabric.

Finally he told her his secret. He said to her, "My hair has never been cut, for I have been dedicated to God from the time I was conceived. If my head were shaved, my strength would leave me; I would become weak, and be just like all other men."

She made him go to sleep on her lap and then called a man in to shave off the seven braids of his hair. She made him vulnerable and his strength left him.

His hair began to grow back after it had been shaved off.
