Jewish views on slavery

https://en.wikipedia.org/wiki/Jewish_views_on_slavery

 Broadly, the Biblical and Talmudic laws tended to consider slavery a form of contract between persons, theoretically reducible to voluntary slavery, unlike chattel slavery, where the enslaved person is legally rendered the personal property (chattel) of the slave owner. Hebrew slavery was prohibited during the Rabbinic era for as long as the Temple in Jerusalem is not reconstructed (i.e., the last two millennia). Although not prohibited, Jewish ownership of non-Jewish slaves was constrained by Rabbinic authorities since non-Jewish slaves were to be offered conversion to Judaism during their first 12-months term as slaves. If accepted, the slaves were to become Jews, hence redeemed immediately. If rejected, the slaves were to be sold to non-Jewish owners. Accordingly, the Jewish law produced a constant stream of Jewish convertors with previous slave experience. Additionally, Jews were required to redeem Jewish slaves from non-Jewish owners, making them a privileged enslavement item, albeit temporary. The combination has made Jews less likely to participate in enslavement and slave trade.
