The seventh aliyah begins with the prohibition against cursing parents, then the prohibitions of adultery and other forbidden sexual relationships including homosexuality, bestiality, and incest, and relations with a woman who is nida (hasn't properly gone to the mikvah).

Finally, the aliyah ends with G-d telling us that he has given us a land flowing with milk and honey, and he has separated us from the nations with his commandments. By doing the commandments we connect to G-d and are sanctified and holy which is what the name of this parsha, "Kedoshim", means.
