first chapter of the Mishnah; chapter 2 to 2-3; chapter 3 to 4-5; chapter 4 to 6; chapter 5 to 7; chapter 6 to 8; chapter 7 to 9. The Tosefta differs greatly from the Mishnah in the enumeration of the blemishes and in their names. In addition to names of blemishes, the Tosefta expands on different scenarios in which a Kohen may find himself when determining the status of a first-born, for example when a creature gives birth to an animal resembling another species. Talmud The Jerusalem Talmud does not contain a tractate Bekhorot. The Babylonian Talmud contains such a tractate, where it has the third place in the Seder. In addition to the common theme of purity, the Babylonian Talmud expands on the exemption of the first-born Levite, or Kohen. The child of a Levite mother, or Kohenim, regardless whether or not the father is a Levite or Israelite, is automatically exempt from the "toll". This exemption is due to the notion that first-born males are already born in the service of God thus redemption is not needed.
