Judges 16:21

18 And when Delilah saw that he had told her all his heart, she sent and called for the lords of the Philistines, saying, Come up this once, for he hath disclosed to me all his heart. Then the lords of the Philistines came up to her and brought money in their hand.

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

20 And 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 before, and shake myself. And he knew not that the LORD had departed from him.

21 But the Philistines took him and put out his eyes, and brought him down to Gaza, and bound him with fetters of brass; and he did grind in the prison-house.

22 However the hair of his head began to grow again after he was shaved.

23 Then the lords of the Philistines assembled to offer a great sacrifice to Dagon their god, and to rejoice: for they said, Our god hath delivered Samson our enemy into our hand.

24 And when the people saw him, they praised their god: for they said, Our god hath delivered into our hands our enemy, and the destroyer of our country; who slew many of us.
