Judges 16:18

And when Delilah saw, judging from his entire attitude, that he had told her all his heart, she sent and called for the lords of the Philistines, who had evidently become doubtful as to results, saying, Come up this once, for he hath showed me all his heart. Then the lords of the Philistines came up unto her and brought money in their hand, for Delilah would undoubtedly not have gone ahead with her betrayal of her lover unless she had had the definite assurance that the money which she coveted would be forthcoming.
