JMNT(i)
15 "There is nothing (not even one thing) from outside a person (a human) which, progressively entering into him, continues having power (is continuing able) to make him ritually defiled or unclean (or: can contaminate him or make him common). But to the contrary, the things habitually issuing forth from out of the person (human) – these things are habitually ritually defiling (contaminating; making common and unclean) the person (humanity). [comment: cf Hag. 2:4-19; here is a reverse-contagion: the Land is clean by the Spirit]
