being otherwise destroyed or discarded. The completion of the Torah scroll is a cause for great celebration, and honoured guests of the individual who commissioned the Torah are invited to a celebration wherein each of the honored guests is given the opportunity to write one of the final letters. It is a great honour to be chosen for this. Commandment to write a scroll It is a religious duty or mitzvah for every Jewish male to either write or have written for him a Torah scroll. Of the 613 commandments, one – the 82nd as enumerated by Rashi, and the final as it occurs in the text the Book of Deuteronomy () – is that every Jewish male should write a Torah scroll in his lifetime.

It is considered a tremendous merit to write (or commission the writing of) a Torah scroll, and a significant honour to have a Torah scroll written in one's honour or memory. Professional scribes (soferim) In modern times, it is usual for some scholars to become soferim and to be paid to complete a Torah scroll under contract on behalf of a community or by individuals to mark a special occasion or commemoration.

A chumash contains the Torah and other writings, usually organised for liturgical use, and sometimes accompanied by some of the main classic commentaries.
