Le Deutéronome 28:27 Halakha : Mishneh Torah, Tefillin, Mezuzah and the Torah Scroll

But if the scribe wrote defective a word that should be plene or vice versa; or a word traditionally pronounced differently to the way it is written, according to the traditional pronunciation, for example, if he wrote Yishkevenoh instead of Yishgelenoh, or Oovatechorim instead of Oova-apolim, etc.; or if he wrote an "open" section as if it were a closed section or vice versa; or if he wrote one of the Songs like the ordinary prose text, or an ordinary section in the form of one of the Songs, the scroll is unfit for use as a scroll of the Law. It has not the sacredness of a scroll of the Law, but is like any one of the books of the Pentateuch out of which children are taught.
