Matthew 15:18

JMNT(i) 18 "Yet the things constantly emerging and flowing forth out of the mouth are continually coming forth from out of the midst of the heart (the core of the individual; the self as a whole, at its deepest level, which is the individual's animating and driving force [note: I owe these last phrases to Marcus Borg, The Heart of Christianity]) and those things continually make the person contaminated, defiled, ceremonially unclean and common.
