The Gentile Slave

"You shall have them serve you forever"Leviticus 25:46.

One who acquires a gentile slave must retain his services for perpetuity. The slave is only granted freedom in the event that the master causes him irreversible personal injury.

Returning a Runaway Slave who Flees to Israel

"You shall not deliver a servant to his master"Deuteronomy 23:16.

It is forbidden to return a non-Jewish slave to his master (even if he is Jewish) if he has escaped and fled to Israel. Rather, the slave must be given his freedom, and he must compensate his former master for his loss (i.e., his own monetary value). This because the slave has come to find refuge in the pure land that G‑d chose for His esteemed nation.

Hurtful Words to the Runaway Slave

"He shall dwell with you do not oppress him"Deuteronomy 23:17.

It is forbidden to verbally distress or humiliate a runaway slave. Though it is forbidden to humiliate anyone, especially a convert, one who does so to a runaway slave transgresses this additional prohibition, too.
