Judges 16:4-5, 19-20

Some time later, he fell in love with a woman in the Valley of Sorek whose name was Delilah. The rulers of the Philistines went to her and said, “See if you can lure him into showing you the secret of his great strength and how we can overpower him so we may tie him up and subdue him. Each one of us will give you eleven hundred shekels of silver.”

After 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. And his strength left him. Then 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.
