Mark 16:14-18

14Afterwards as they lay at table he was manifested to the eleven, and reproached [them with] their unbelief and hardness of heart, because they had not believed those who had seen him risen.

15And he said to them, Go into all the world, and preach the glad tidings to all the creation.

16He that believes and is baptised shall be saved, and he that disbelieves shall be condemned.

17And these signs shall follow those that have believed: in my name they shall cast out demons; they shall speak with new tongues;

18they shall take up serpents; and if they should drink any deadly thing it shall not injure them; they shall lay hands upon the infirm, and they shall be well.
