Matthew 15:19

19. Out of the heart The fountain of the moral intention and the moral action. Sinful action flows forth from a sinful nature. There lies back of the bad action a permanent badness of the disposition. The heart is therefore depraved. Evil thoughts The word thoughts here refers to these internal reasonings and weighing for and against yielding to sin which precede its commission. The heart parleys with crime and fluctuates before it gives forth the act. Hence the phrase evil thoughts designates the springs from which proceed the whole catalogue of sins enumerated in the verse. This catalogue follows nearly the order of the second table of the decalogue, beginning with the sixth commandment. False witness This phrase includes false testimony, or lying of every kind. Blasphemies Injurious expressions against God or man.
