Matthew 15:19 - Ellicott's Commentary On The Whole Bible

Evil thoughts,... blasphemies. — The plural form points to the manifold variety of the forms of guilt under each several head. The order is in some measure an ascending one, beginning with the “thoughts,” or rather trains of thought, which are the first suggestions of evil, and ending in the “blasphemies” or revilings which, directly or indirectly, have God and not man for their object. In this beginning and end we may trace a reference to those “evil surmises” which had led the Pharisees, as in Matthew 12:24, to words which were blasphemy against the Son of Man, and came perilously near to the blasphemy against the Holy Spirit.
