'Hair' in the Bible

"When hair grows long in Israel, when the people give themselves willingly, bless the LORD!

for indeed, you will conceive and give birth to a son. You must never cut his hair, because the boy will be a Nazirite to God from birth, and he will begin to save Israel from the power of the Philistines.”

Then Delilah said to Samson, “Up to now you have deceived me and told me lies; tell me how you may be bound.” And he said to her, “If you weave the seven locks of my hair with the web [and fasten it with a pin, then I will become weak and be like any other man.”

So Delilah took the seven locks on his head and wove them into the loom while he slept. She fastened his hair with a peg and then told him, "The Philistines are attacking you, Samson!" But he woke up from his nap and pulled the pin from the loom and the weaving.

he told her the whole truth and said to her, “My hair has never been cut, because I am a Nazirite to God from birth. If I am shaved, my strength will leave me, and I will become weak and be like any other man.”

So she enticed him to fall asleep on her lap, called for a man to shave off his seven locks of hair from his head, and so began to humiliate him. Then his strength abandoned him.

Howbeit the hair of his head began to grow again after he was shaven.

Among all this people there were seven hundred chosen men lefthanded; every one could sling stones at an hair breadth, and not miss.
