Halakhah su Deuteronomio 12:4

Whoever destroys sacred writings violates the negative commandment, "Do not act in this manner to Hashem your God."⁸Deuteronomy 12:4. We must protest against those bookbinders who paste sacred writings in the bookcovers. You also must be very careful when you give old, sacred books to a non-Jewish bookbinder. You should remove the old covers and hide them so that the bookbinder will not install them in secular books.

Not to destroy things upon which His name, may He be blessed, are called: That we should not destroy and erase the things upon which the name of the Holy One, blessed be He, are called, such as the Temple and holy books and His precious names, blessed be He. And about all this is it stated (Deuteronomy 12:4), "Do not do this to the Lord, your God." After it was preceded by the commandment to destroy idolatry and to erase its name and to demolish all of its houses and altars, it prevented [it here] and stated, "Do not do this to the Lord, your God." And at the end of Tractate Makkot 22a, they, may their memory be blessed, said "One who burns consecrated wood is lashed, and its warning is from 'and you shall destroy their name from that place[...] Do not do this, etc.'" And so too did they say there that one who erases the name [of God] is lashed, and its warning is from the very same verse.
