The major change found in the Talmud's slavery laws was that a single set of rules, with a few exceptions, governs both Jewish slaves and non-Jewish slaves. Another change was that the distinction between Hebrew and non-Hebrew slaves began to diminish as the Talmud expanded during this period. This included an expanded set of obligations the owner incurred toward the slave as well as codifying the process for manumission (the freeing from slavery). It also included a large set of conditions, that allowed or required manumission to include requirements for education of slaves, expanding disability manumission, and in cases of religious conversion or necessity. These restrictions were based on the Biblical injunction to treat slaves well with the reinforcement of the memory of Egyptian slavery which Jews were urged to remember by their scriptural texts. However, historian Josephus wrote that the seven-year automatic release was still in effect if the slavery was a punishment for a crime the slave committed (as opposed to voluntary slavery due to poverty). In addition, the notion of Canaanite slaves from the Jewish Bible is expanded to all non-Jewish slaves.
