Thou shalt not uncover the nakedness of thy mother’s sister: for she is thy mother’s near kinswoman.
The prohibition belongs to the wider boundaries in Leviticus 18:6-19 that God set to preserve the moral purity of His people, and within those boundaries sexual relations with a mother's sister are forbidden. The command not to uncover nakedness warns against sexual familiarity between men and women. To violate this boundary is both a crime and a sin before God.
