וַתֵּ֣רֶא דְלִילָ֗ה כִּֽי־הִגִּ֣יד לָהּ֮ אֶת־כָּל־לִבּוֹ֒ וַתִּשְׁלַ֡ח וַתִּקְרָא֩ לְסַרְנֵ֨י פְלִשְׁתִּ֤ים לֵאמֹר֙ עֲל֣וּ הַפַּ֔עַם כִּֽי־הִגִּ֥יד לה [לִ֖י] אֶת־כָּל־לִבּ֑וֹ וְעָל֤וּ אֵלֶ֙יהָ֙ סַרְנֵ֣י פְלִשְׁתִּ֔ים וַיַּעֲל֥וּ הַכֶּ֖סֶף בְּיָדָֽם׃

And when Delilah saw that he had told her all his heart, she sent and called for the lords of the Philistines, saying: ‘Come up this once, for he hath told me all his heart.’ Then the lords of the Philistines came up unto her, and brought the money in their hand.
