'Hair' in the Bible

The next day, a man escaped from Saul's camp! With torn clothes and dirty hair, he approached David, fell to the ground, and bowed down to him.

Then she said, "Your majesty, please remember the LORD your God, so that blood avengers don't do any more damage! Otherwise, they'll destroy my son!" So he promised, "As the LORD lives, not even a single hair from your son's head will fall to the ground!"

Whenever he cut his hair he cut it at the end of every year, because it grew thick on his head, which is why he cut it his hair weighed in at 200 shekels measured by the royal standard.
