7 And Samson said to her, If seven new bow-cords which have never been made dry are knotted round me, I will become feeble and will be like any other man. 8 So the chiefs of the Philistines gave her seven new bow-cords which had never been made dry, and she had them tightly knotted round him. 9 Now she had men waiting secretly in the inner room; and she said to him, The Philistines are on you, Samson. And the cords were broken by him as a twist of thread is broken when touched by a flame. So the secret of his strength did not come to light.

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.
