Judges 16:19-21

19And she made him sleep on her knees, and called for a man and had him shave off the seven locks of his head. Then she began to humble him, and his strength left him.

20She said, “The Philistines are upon you, Samson!” And he awoke from his sleep and said, “I will go out as at other times and shake myself free.” But he did not know that 1the Lord had departed from him.

21Then the Philistines seized him and gouged out his eyes; and they brought him down to Gaza and restrained him with bronze chains, and he became a grinder in the prison.
