[306] However, he at length ¹ transgressed the laws of his country, and altered his own regular way of living, and imitated the strange customs of foreigners, which thing was the beginning of his miseries; for he fell in love with a woman that was a harlot among the Philistines: her name was Delilah, and he lived with her. So those that administered the public affairs of the Philistines came to her, and, with promises, induced her to get out of Samson what was the cause of that his strength, by which he became unconquerable to his enemies. Accordingly, when they were drinking, and had the like conversation together, she pretended to admire the actions he had done, and contrived to get out of him by subtlety, by what means he so much excelled others in strength. Samson, in order to delude Delilah, for he had not yet lost his senses, replied, that if he were bound with seven such green withs of a vine as might still be wreathed, he should be weaker than any other man. The woman said no more then, but told this to the rulers of the Philistines, and hid certain of the soldiers in ambush within the house; and when he was disordered in drink and asleep, she bound him as fast as possible with the withs; and then upon her awakening him, she told him some of the people were upon him; but he broke the withs, and endeavored to defend himself, as though some of the people were upon him. Now this woman, in the constant conversation Samson had with her, pretended that she took it very ill that he had such little confidence in her affections to him, that he would not tell her what she desired, as if she would not conceal what she knew it was for his interest to have concealed. However, he deluded her again, and told her, that if they bound him with seven cords, he should lose his strength. And when, upon doing this, she gained nothing, he told her the third thee, that his hair should be woven into a web; but when, upon doing this, the truth was not yet discovered, at length Samson, upon Delilah's prayer, (for he was doomed to fall into some affliction,) was desirous to please her, and told her that God took care of him, and that he was born by his providence, and that "thence it is that I suffer my hair to grow, God having charged me never to poll my head, and thence my strength is according to the increase and continuance of my hair." When she had learned thus much, and had deprived him of his hair, she delivered him up to his enemies, when he was not strong enough to defend himself from their attempts upon him; so they put out his eyes, and bound him, and had him led about among them.
