In Leviticus 15:5, touching the bed of a discharge person also defiles — a parallel rule about uncleanness from contact with the same source.

In Leviticus 15:8, spittle from the discharge person defiles — another case of the same impurity laws for contact with discharges.

In Leviticus 15:13, the cleansing procedure for the discharge person is given, completing the impurity process touched on here.

In Leviticus 14:46, entering a house with mildew also brings uncleanness until evening — a similar impurity law from a different source.

Leviticus 17:15 applies the same washing and uncleanness-until-evening rule to eating unclean meat — parallel but different cause.
