Mark 16:18-20

they will pick up serpents, and if they drink anything deadly, it will not hurt them; they will lay hands on the sick, and they will get well.” So then, when the Lord Jesus had spoken to them, He was taken up into heaven and sat down at the right hand of God. [Ps 110:1] And they went out and preached everywhere, while the Lord was working with them and confirming the word by the signs that followed.]
