Daily Aliya for Kedoshim, Revii (4th Aliya)
Aliya Summary: One must not take advantage of the newcomer to the Land (convert and/or stranger). The convert shall be treated with love; we must learn from our Egyptian experience.
It is forbidden to cheat with any false measures, and one must be honest in weights and measures. Clearly there is a reason why this commandment is stated both ways, underscoring the importance of being fair with those with whom we deal with (that statement applies to both converts and business dealings).
