I won't argue the historical point, but of the 10 commandments, only the 4th (about the sabbath) was altered the second time it was written, and included a specific note to remember they were slaves as a part of the reason to rest. (Deuteronomy 5:15) But also to give their own servants rest, something the Orthodox Jews seem to have forgotten or ignore by hiring servants to do work for them on the sabbath.
