This is the first of a five-part presentation of the Mishnaic law of damages. Jacob Neusner provides a translation and explanation of Baba Qamma, the Mishnah tractate that deals with damages done by one’s chattel (oxen) and damages done by oneself, with particular focus on theft. Neusner examines Baba Qamma chapter by chapter, comparing its themes with those found in other Mishnah tractates and other Scripture passages.
