1,893. Learning the Chalitzah Text
Yibum v’Chalitzah 4:3
The yevama and the yavam should be shown how to read until they are familiar with the requisite text. The yevama should be instructed to say “lo avah” (“he did not desire”) in one breath, followed by “yabmi” (“my yavam”) separately so she can’t be understood to have said “avah yabmi” (“my yavam desired”).
Yibum v’Chalitzah 4:4
If the yevama knows the text that she has to recite, we are not particular about her reading “lo avah” in one breath but if she’s not able, she is coached until she does so.
