Today's daf is dedicated for a refuah shleima to Naaran ben Rachel Perla who was injured yesterday and to all those injured over the past few weeks.  Rav Yehuda rules that a kohen gadol who betroths a widow (or a regular kohen with a woman who is forbidden to him) gets two sets of lashes - one for "do not take her" and one for "do not desecrate your seed" which is understood to be referring to making the woman a chalala. A few questions are raised against Rav Yehuda's statement. Abaye and Rava disagree about whether lashes are given even if one betrothed a woman without having relations with her or only if they also had relations. In what situations are there clear exceptions to the rules? What is the logical argument to support Rabbi Yehuda's opinion that the daughter of a male convert cannot marry a kohen? Rabbi Yehuda and those who disagree with him derive their positions from a verse in Ezekiel 44:22 - as each understands the verse differently. How is the continuation of that verse meant to be understood? There is a debate about whether a father is believed to say his son is a mamzer or if both parents say the child is a mamzer. Both opinions derive their opinions from the laws of 'yakir' the right of the father to declare which son is the firstborn - can we say this is true for disqualifying the child as well or not?
