Judges 16:17-20

17So 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.” 18When Delilah saw that he had told her everything, she sent word to the rulers of the Philistines, “Come back once more; he has told me everything.” So the rulers of the Philistines returned with the silver in their hands.

19After putting him to sleep on her lap, she called for someone to shave off the seven braids of his hair, and so began to subdue him. Hebrew; some Septuagint manuscripts and he began to weaken And his strength left him.

20Then she called, “Samson, the Philistines are upon you!” He awoke from his sleep and thought, “I’ll go out as before and shake myself free.” But he did not know that the LORD had left him.
