Morality

[The Grand Nudger]

There was no economic necessity.  You're excusing the faith tradition, giving it a mulligan while simultaneously asserting that it was qualitatively not based on the same silly horseshit as american slavery.

American slavers referred directly to it. They also swore it was a necessity. Magic book commands slaves to obey their masters...among other things.

The Biblical texts outline sources and legal status of slaves, economic roles of slavery, types of slavery, and debt slavery, which thoroughly explain the institution of slavery in Israel in antiquity.[1] Each section – Exodus 21, Deuteronomy 15, and Leviticus 25 – provides an outlook into the understanding of recent slave relations and gives guidance to the Israelites on how to further their life in a proper manual.[1] Philo, one of the philosophers of the time, wrote texts on how to properly treat slaves, indicating that slavery was an important part of Jewish life, but also emphasizes the humanitarian perspective offered up by many Ancient Near East scholars.[2] One such way of showing this was through the sharing of products, such as food and cloth, with other, underprivileged members of society.[1]
