Mark 16:17 in the King James Version
And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues;
Context
16 He who believes and is baptized will be saved; but he who disbelieves will be condemned.
17 These signs will accompany those who believe: in my name they will cast out demons; they will speak with new languages;
18 they will take up serpents; and if they drink any deadly thing, it will in no way hurt them; they will lay hands on the sick, and they will recover.”
