Judges 16:18-20

18When Delilah realized that he had told her the whole truth, she sent this message to the Philistine leaders: “Come one more time, for he has told me the whole truth.” The Philistine leaders came to her and brought the silver with them.

19Then she let him fall asleep on her lap and called a man to shave off the seven braids on his head. In this way, she made him helpless, and his strength left him.

20Then she cried, “Samson, the Philistines are here!” When he awoke from his sleep, he said, “I will escape as I did before and shake myself free.” But he did not know that the Lord had left him.
