15 Then she said to him, "How can you say, 'I love you,' when your heart is not with me? You have mocked me these three times, and have not told me where your great strength lies." 16 And it came to pass, when she pestered him daily with her words and pressed him, so that his soul was vexed to death, 17 that he told her all his heart, and said to her, "No razor has ever come upon my head, for I have been a Nazirite to God from my mother's womb. If I am shaven, then my strength will leave me, and I shall become weak, and be like any other man."
Matthew Henry's Commentary on Judges 16:15-17
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.
