The first halizah has finally severed the levirate bond between the levir or the levirs and the widow or the widows. The second halizah is, therefore, valueless. ');">¹⁸</span> THE SAGES, HOWEVER, SAID: A LETTER OF DIVORCE HAS VALIDITY AFTER ANOTHER LETTER OF DIVORCE,<span class="x" onmousemove="('comment',' The relatives of the second widow are, therefore, forbidden to the levir (as relatives of his legal divorcee), and the relatives of the one widow are similarly forbidden to the second levir. The first letter of divorce, the Sages maintain, is only partially valid since halizah also is required. The levirate bond consequently is not thereby completely severed and the second divorce brings the widow under the category of a divorced woman. Cf supra 327 n. 1.

The second ma'amar, since it was made before consummation had taken place, is, therefore, valid. ');">²⁰</span>
