Judges 14:17

And she wept before him the seven days, while the feast
lasted
Those that remained of the seven days, from the fourth to this time, as Kimchi seems rightly to interpret it; though some think she began to beseech him with tears, on the first day of the feast, to impart the secret to her for her own satisfaction; and then, after the men had urged her on the fourth day to persuade her husband to it, she continued pressing him more earnestly with tears unto the seventh day. Some, as Abarbinel observes, and to whom he seems to incline, think there were fourteen days, seven days before the festival began, on the last of which they importuned her to try to get the secret from him, ( Judges 14:15 ) , and that she continued pressing all the second seven days; but it seems quite clear that it was at the beginning of the seven days of the feast that the riddle was put, which was to be explained within that time, ( Judges 14:12 )

and it came to pass on the seven day, that he told her, because she lay
sore upon him;
pressed him most earnestly with her entreaties, cries, and tears:

and she told the riddle to the children of her people;
though she knew it would be to her husband's detriment, and that he must be obliged to give them thirty sheets of linen, and as many suits of apparel, and though it is probable she had promised not to tell them.
