Judges 16:19-21

19And she made him sleep upon her knees; and she called for a man, and shaved off the seven locks of his head; and she began to afflict him, and his strength went from him. 20And she said, The Philistines are upon thee, Samson. And he awoke out of his sleep, and said, I will go out as at other times, and shake myself free. But he knew not that Jehovah was departed from him. 21And the Philistines laid hold on him, and put out his eyes; and they brought him down to Gaza, and bound him with fetters of brass; and he did grind in the prison-house.
