2,013. More Things That Invalidate the Scroll

Hilchos Sotah 4:8

If the kohein wrote the curses in the form of a letter, it’s invalid because the Torah specifies “in a scroll.” If he wrote it on two pages, it’s invalid because the Torah specifies “in a scroll” - i.e., on one page, not two or three. The curses may not be written on paper or untreated parchment; they may only be written in a parchment scroll as specified by the Torah. If the curses are written on paper or untreated parchment, the document is not usable.

Hilchos Sotah 4:9

If the scroll is written by a Yisroel (an “Israelite,” i.e., a rank-and-file Jew) or by a kohein who’s a minor, it is invalid because Numbers 5:23 specifies, “the kohein shall write.” The scroll may not be written with resin, vitriol or any other indelible substance. He must use ink without vitriol because the Torah specifies that he will write it and then blot it out, from which we see that it must be written using something that can be blotted out. If he writes the scroll using an indelible substance, it is unusable.
