15 She said, "How can you say 'I love you' when you won't even trust me? Three times now you've toyed with me, like a cat with a mouse, refusing to tell me the secret of your great strength." 16 She kept at it day after day, nagging and tormenting him. Finally, he was fed up - he couldn't take another minute of it. 17 He spilled it. He told her, "A razor has never touched my head. I've been God's Nazirite from conception. If I were shaved, my strength would leave me; I would be as helpless as any other mortal."
18 When Delilah realized that he had told her his secret, she sent for the Philistine tyrants, telling them, "Come quickly - this time he's told me the truth." They came, bringing the bribe money. 19 When she got him to sleep, his head on her lap, she motioned to a man to cut off the seven braids of his hair. Immediately he began to grow weak. His strength drained from him. 20 Then she said, "The Philistines are on you, Samson!" He woke up, thinking, "I'll go out, like always, and shake free." He didn't realize that God had abandoned 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.
