Dunghill (koprian). Later word in the Koin vernacular. Here only in the N.T., though in the LXX. Men cast it out (exw ballousin auto). Impersonal plural. This saying about salt is another of Christ's repeated sayings ( Matthew 5:13 ; Mark 9:50 ). Another repeated saying is the one here about having ears to hear ( Luke 8:8 ; 11:15 Mt 14:35 ; 13:43 Mt 14:35 ).
