Gittin 43 - June 28, 9 Tamuz

Can a master sell the potential k'nas (fine) payment that the master would receive in the event that an ox gored his/her slave and killed him? They bring a source to answer the question, but it is inconclusive. There is a debate regarding a half-slave/half-free man who betroths a woman or a man who betroths a woman who is half maidservant/half-free - is the kiddushin valid? Is it the same as one who betroths half a woman or is there reason to distinguish between the cases? If she was betrothed before she was entirely freed and then freed, does the emancipation cancel the kiddushin or complete it? There was a case where they forced an owner to release his half-maidservant/half-free woman. Was it because they held like Rabbi Yochanan ben Broka that also women are commanded to procreate or was it to protect her as men were taking advantage of her since she was unable to be married? The rabbis penalized those who sold their slaves to a Gentile or Jewish owner outside of Israel. Do they need to also give them an emancipation document? If one used a slave as collateral for a loan to a gentile, at what stage is the slave considered freed?
