Commentary for Ruth 3:18

וַתֹּ֙אמֶר֙ שְׁבִ֣י בִתִּ֔י עַ֚ד אֲשֶׁ֣ר תֵּֽדְעִ֔ין אֵ֖יךְ יִפֹּ֣ל דָּבָ֑ר כִּ֣י לֹ֤א יִשְׁקֹט֙ הָאִ֔ישׁ כִּֽי־אִם־כִּלָּ֥ה הַדָּבָ֖ר הַיּֽוֹם׃

Then said she: ‘Sit still, my daughter, until thou know how the matter will fall; for the man will not rest, until he have finished the thing this day.’
