וַיֹּאמֶר אִם־שָׁמוֹעַ תִּשְׁמַע לְקוֹל יְהוָה אֱלֹהֶיךָ וְהַיָּשָׁר בְּעֵינָיו תַּעֲשֶׂה וְהַאֲזַנְתָּ לְמִצְוֹתָיו וְשָׁמַרְתָּ כָּל־חֻקָּיו כָּל־הַמַּחֲלָה אֲשֶׁר־שַׂמְתִּי בְמִצְרַיִם לֹא־אָשִׂים עָלֶיךָ כִּי אֲנִי יְהוָה רֹפְאֶךָ ׃ ס

And said, If thou wilt diligently hearken to the voice of the LORD thy God, and wilt do that which is right in his sight, and wilt give ear to his commandments, and keep all his statutes; I will put none of these diseases upon thee, which I have brought upon the Egyptians; for I am the LORD that healeth thee.
