Judges 16:14-24

14 And she fastened it with the pin, and said unto him, "The Philistines be upon thee, Samson." And he awakened out of his sleep, and went away with the pin of the beam and with the web.
15 And she said unto him, "How canst thou say, `I love thee,' when thine heart is not with me? Thou hast mocked me these three times, and hast not told me wherein thy great strength lieth."
16 And it came to pass, when she pressed him daily with her words and urged him, so that his soul was vexed unto death,
17 that he told her all his heart and said unto her, "There hath not come a razor upon mine head, for I have been a Nazirite unto God from my mother's womb. If I be shaven, then my strength will go from me, and I shall become weak and be like any other man."
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 shown me all his heart." Then the lords of the Philistines came up unto 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 be 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 grinding in the prison house.
22 However the hair of his head began to grow again after he was shaven.
23 Then the lords of the Philistines gathered together to offer a great sacrifice unto 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."
