Lalu Ratu Ester, anak perempuan Abihail, bersama Mordekhai, orang Yahudi itu, menulis dengan segala kewibawaan untuk meneguhkan surat Purim yang kedua ini.
Mishneh Torah, Scroll of Esther and Hanukkah
All of a Scroll needs to be sewn to the point that all of its hides be one scroll. And it can only be sewn with sinews, like a Torah [scroll]. So if one sewed it without sinews, it is disqualified. But one is not required to sew all of its pages with sinews, like a Torah [scroll]. Rather even if he sewed three stitches with sinews at the end of the page, three in the middle and three at the other end, it is fit — since it is called a letter (iggeret).
