7 Samson told her, "If they were to tie me up with seven bowstrings - the kind made from fresh animal tendons, not dried out - then I would become weak, just like anyone else." 8 The Philistine tyrants brought her seven bowstrings, not dried out, and she tied him up with them. 9 The men were waiting in ambush in her room. Then she said, "The Philistines are on you, Samson!" He snapped the cords as though they were mere threads. The secret of his strength was still a secret.

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.
