15 And she said to him, Why do you say you are my lover when your heart is not mine? Three times you have made sport of me, and have not made clear to me the secret of your great strength. 16 So day after day she gave him no peace, for ever questioning him till his soul was troubled to death. 17 And opening all his heart to her, he said to her, My head has never been touched by a blade, for I have been separate to God from the day of my birth: if my hair is cut off, then my strength will go from me and I will become feeble, and will be like any other man.
18 And when Delilah saw that he had let her see into his heart, she sent word to the chiefs of the Philistines saying, Come up this time, for he has let out all his heart to me. Then the chiefs of the Philistines came to her, with the money in their hands. 19 And she made him go to sleep on her knees; and she sent for a man and had his seven twists of hair cut off; and while it was being done he became feeble and his strength went from him. 20 Then she said, The Philistines are on you, Samson. And awaking from his sleep, he said, I will go out as at other times, shaking myself free. But he was not conscious that the Lord had gone from him.

Commentary on Judges 16:4-17
(Read Judges 16:4-17)
Samson had been more than once brought into mischief and danger by the love of women, yet he would not take warning, but is again taken in the same snare, and this third time is fatal. Licentiousness is one of the things that take away the heart. This is a deep pit into which many have fallen; but from which few have escaped, and those by a miracle of mercy, with the loss of reputation and usefulness, of almost all, except their souls. The anguish of the suffering is ten thousand times greater than all the pleasures of the sin.
Commentary on Judges 16:18-21
(Read Judges 16:18-21)
See the fatal effects of false security. Satan ruins men by flattering them into a good opinion of their own safety, and so bringing them to mind nothing, and fear nothing; and then he robs them of their strength and honour, and leads them captive at his will. When we sleep our spiritual enemies do not. Samson's eyes were the inlets of his sin, verse 1, and now his punishment began there. Now the Philistines blinded him, he had time to remember how his own lust had before blinded him. The best way to preserve the eyes, is, to turn them away from beholding vanity. Take warning by his fall, carefully to watch against all fleshly lusts; for all our glory is gone, and our defence departed from us, when our separation to God, as spiritual Nazarites, is profaned.
