Jesus repeated and became more specific so the disciples would understand Him. The list of sins proceeds from six actions to six attitudes (cf. Romans 1:29-31; Galatians 5:19-23). Matthew"s record included only six sins. Evil thoughts are the ground out of which the evil actions and attitudes grow. The order in the text is true to life. Sin proceeds from the heart (human nature) to the thoughts (human mind) to actions (human deeds). [source][source][source]
This controversy with the Pharisees and the scribes was a factor that led Jesus to withdraw from Galilee a third time (cf. Mark 4:35-36; Mark 6:31-32). [source][source][source]
