Mark 16:15-20 New American Standard Bible (NASB)
15 And He said to them, “Go into all the world and preach the gospel to all creation. 16 The one who has believed and has been baptized will be saved; but the one who has not believed will be condemned. 17 These signs will accompany those who have believed: in My name they will cast out demons, they will speak with new tongues; 18 they will pick up serpents, and if they drink any deadly poison, it will not harm them; they will lay hands on the sick, and they will recover.”
19 So then, when the Lord Jesus had spoken to them, He was received up into heaven and sat down at the right hand of God. 20 And they went out and preached everywhere, while the Lord worked with them, and confirmed the word by the signs that followed.]]
[[[a]And they promptly reported all these instructions to Peter and his companions. And after that, Jesus Himself also sent out through them from east to west the sacred and imperishable proclamation of eternal salvation.]]
Mark 16:15-20 New International Version (NIV)
15 He said to them, “Go into all the world and preach the gospel to all creation. 16 Whoever believes and is baptized will be saved, but whoever does not believe will be condemned. 17 And these signs will accompany those who believe: In my name they will drive out demons; they will speak in new tongues; 18 they will pick up snakes with their hands; and when they drink deadly poison, it will not hurt them at all; they will place their hands on sick people, and they will get well.”
19 After the Lord Jesus had spoken to them, he was taken up into heaven and he sat at the right hand of God. 20 Then the disciples went out and preached everywhere, and the Lord worked with them and confirmed his word by the signs that accompanied it.
