"Practically every society that possessed slaves wrote about them in its laws, and thus only a few codes can be mentioned here. The ancient Mesopotamian laws of
Eshnunna (
c. 1900 BCE) and the
Code of Hammurabi had a number of articles devoted to slavery, as did the Pentateuch. In ancient
India the
Laws of Manu of the 1st century BCE contained numerous laws on slaves."

If you killed one of my slaves, ... it would only be fair that I would get to kill one of yours.
