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

We may think that if the person was once a slave, he is used to being mistreated and, therefore, we do not have to watch out for his feelings.

The Torah cautions us not to think this way about a slave and never to say anything that may hurt his feelings.

We are commanded to be considerate and kind towards a runaway slave, welcoming him and treating him with respect.
