'Hair' in the Bible

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

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.

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.

But the hair on his head began to grow again after it had been shaved off.

Out of all these soldiers, 700 of them were left-handed and each one could sling a stone at a hair and never miss.
