Mark 16:15-19

16:15 He said to them, “Go into all the world and preach the gospel to every creature. 16:16 The one who believes and is baptized will be saved, but the one who does not believe will be condemned. 16:17 These signs will accompany those who believe: In my name they will drive out demons; they will speak in new languages; ¹  16:18 they will pick up snakes with their hands, and whatever poison they drink will not harm them; ²  they will place their hands on the sick and they will be well.” 16:19 After the Lord Jesus had spoken to them, he was taken up into heaven and sat down at the right hand of God.

[16:17]  ¹ tn Grk “tongues,” though the word is used figuratively (perhaps as a metonymy of cause for effect).
