Judges 16:16-17 NIV
With such nagging she prodded him day after day until he was sick to death of it.
So he told her everything. “No razor has ever been used on my head,” he said, “because I have been a Nazirite dedicated to God from my mother’s womb. If my head were shaved, my strength would leave me, and I would become as weak as any other man.”
