Old Testament

Mark 16:14-18
14Later, he appeared to the Eleven themselves as they were reclining at the table. He rebuked them for their unbelief and hardness of heart, because they did not believe those who had seen him after he had risen.
15He said to them, “Go into all the world and preach the gospel to all creation. 16Whoever believes and is baptized will be saved, but whoever does not believe will be condemned.
17“These signs will accompany those who believe: In my name they will drive out demons. They will speak in new languages. 18They will pick up snakes. And if they drink any deadly poison, it will not harm them. They will lay their hands on the sick, and they will get well.”
