Judges 16:19-21

19And she made him sleep upon her knees, and called a man, and she caused him to shave off the seven locks of his head; and she began to overpower him, and his strength went from him.

20And she said, The Philistines are upon thee, Samson! And he awoke out of his sleep, and thought, I will go out as at other times before, and disengage myself. And he knew not that Jehovah had departed from him.

21And the Philistines seized him, and put out his eyes, and brought him down to Gazah, and bound him with fetters of bronze; and he had to grind in the prison-house.
