The opening as it read in October 6, 2023

Yevamot ( , "Brother's Widow", also pronounced Yevamos, or Yavmus) is a tractate of the Talmud that deals with, among other concepts, the laws of Yibbum ( ייבום , loosely translated in English as levirate marriage ), and, briefly, with conversion to Judaism . This tractate is the first in the order of Nashim ( נשים , "Women"). Yevamot, along with Eruvin and Niddah , is considered one of the three most difficult tractates in the Babylonian Talmud . A Hebrew mnemonic for the three is עני ( ani , meaning "poverty").
