יֶ֤תֶר הַגָּזָם֙ אָכַ֣ל הָֽאַרְבֶּ֔ה וְיֶ֥תֶר הָאַרְבֶּ֖ה אָכַ֣ל הַיָּ֑לֶק וְיֶ֣תֶר הַיֶּ֔לֶק אָכַ֖ל הֶחָסִֽיל׃
That which the palmer-worm hath left hath the locust eaten; And that which the locust hath left hath the canker-worm eaten; And that which the canker-worm hath left hath the caterpiller eaten.
