Never mock anyone or look down on anyone - not the tiller of the ground,the builder and plasterer and laborer with soil on the ground is as worthy is the president and royalty ,for remember,that HaShem too,worked with soil and clay and made Adam (with soil and earth )and Eve all of us and HaShem is Highest of All - The Creator of us All.Treat all equally and be forever humble in HaShem's and other's eyes.
