The soul that eateth knowingly; for if it were done ignorantly, a sacrifice was accepted for it, Leviticus 5:2. Having his uncleanness upon him, i.e. not being cleansed from his uncleanness according to the appointment, Leviticus 11:24, &c. This verse speaks of uncleanness from an internal cause, as by an issue, &c., for what was from an external cause is spoken of in the next verse.
