Contradiction with Mark 1:34
This verse contradicts Luke 4:37 by stating that Jesus did not permit the devils to speak, because they knew him, while Luke 4:37 reflects the fame of Jesus spreading throughout the region, implying open acknowledgment and spreading of his deeds.
Mark 1:34: And he healed many that were sick of divers diseases, and cast out many devils; and suffered not the devils to speak, because they knew him. [to speak...: or, to say that they knew him]
