The thirtieth reading from the Torah and seventh reading from Leviticus is named Kedoshim, which mean "holy." The title comes from the words in Leviticus 19:2, which says, "You shall be holy, for I the LORD your God am holy." Leviticus 19 describes the holy community through a series of specific commandments. Leviticus 20 warns against the snares of sexual immorality and idolatry, mandating a death penalty for certain sins. Except in biblical leap years, Kedoshim is read on the same Sabbath as the previous reading, Acharei Mot.
