Therefore speak I to them in parables: because they seeing see not; and hearing they hear not, neither do they understand.
Ver. 13. Therefore speak I to them in parables] Because their wilful blindness and stubbornness deserve I should do it. They are sinners against their own souls, let them rue it therefore.
And hearing they hear not] Audientes corporis sensu, non audiunt cordis assensu, saith Augustine.
