Slavery:
You shall not extradite a slave who fled to your land.
Primary Verses:
Deuteronomy 23:15-16
"Thou
shalt not deliver unto his master the servant which is
escaped from his master unto thee: He
shall dwell with thee, even among you, in that place
which he shall choose in one of thy gates, where it
liketh him best: thou shalt not oppress him."
