Mark 16:14-20

14 And afterward he was manifested unto the eleven themselves as they sat at meat; and he upbraided them with their unbelief and hardness of heart, because they believed not them that had seen him after he was risen.

15 And he said unto them, Go ye into all the world, and preach the gospel to the whole creation.

16 He that believeth and is baptized shall be saved; but he that disbelieveth shall be condemned.

17 And these signs shall accompany them that believe: in my name shall they cast out demons; they shall speak with new tongues;

18 they shall take up serpents, and if they drink any deadly thing, it shall in no wise hurt them; they shall lay hands on the sick, and they shall recover.

19 So then the Lord Jesus, after he had spoken unto them, was received up into heaven, and sat down at the right hand of God.

20 And they went forth, and preached everywhere, the Lord working with them, and confirming the word by the signs that followed. Amen.
