7 And Samson said to her, "If they bind me with seven fresh bowstrings, not yet dried, then I shall become weak, and be like any other man." 8 So the lords of the Philistines brought up to her seven fresh bowstrings, not yet dried, and she bound him with them. 9 Now men were lying in wait, staying with her in the room. And she said to him, "The Philistines are upon you, Samson!" But he broke the bowstrings as a strand of yarn breaks when it touches fire. So the secret of his strength was not known.

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.
