א֣וֹ אִ֗ישׁ אֲשֶׁ֨ר תַּעֲבֹ֥ר עָלָ֛יו ר֥וּחַ קִנְאָ֖ה וְקִנֵּ֣א אֶת־אִשְׁתּ֑וֹ וְהֶעֱמִ֤יד אֶת־הָֽאִשָּׁה֙ לִפְנֵ֣י יְהוָ֔ה וְעָ֤שָׂה לָהּ֙ הַכֹּהֵ֔ן אֵ֥ת כָּל־הַתּוֹרָ֖ה הַזֹּֽאת׃
или когда дух ревности обрушится на человека, и он ревнует над своей женой; тогда он поставит женщину перед Господом, и священник исполнит на ней весь этот закон.
Rashi
If one wrote one letter and erased one letter - onto the water, and then wrote the next letter and erased it, until [in this way] completing [the text] in its entirety, as it is written "all this ritual" [Numbers 5:30] -- that it all be [together] as one.
Rashi
For her sake - in a scroll by itself, as it is written, "and he shall carry out with her" [Numbers 5:30] -- for her sake.
Bartenura
ואין מגילתה כשרה לשקות [בה] סוטה אחרת – for we require writing for her sake, as it is written (there – Numbers 5:30): “and the priest shall carry out [all this ritual with her].” All of the carrying out of the ritual is for her sake.
