An uncomfortable daf, given our modern sensibilities regarding slavery. Note that the Amoraim themselves owned slaves; it wasn't just a biblical practice. Note also, these are "avadim Canaanim," non-Jews who come to live among Jews, and are required to keep some Jewish practices (or perhaps shouldn't be kept as a slave). Some stories, and the halakhic positions that emerge from them. Plus, what if freeing one's slaves violates a Torah commandment? How do we understand the freeing of a slave to make a minyan?
