Mark 16:16-20

¹⁶He who has believed and has been baptized shall be saved; but he who has disbelieved shall be condemned. ¹⁷These signs will accompany those who have believed: in My name they will cast out demons, they will speak with new tongues; ¹⁸they will pick up serpents, and if they drink any deadly poison, it will not hurt them; they will lay hands on the sick, and they will recover.”

¹⁹So then, when the Lord Jesus had spoken to them, He was received up into heaven and sat down at the right hand of God. ²⁰And they went out and preached everywhere, while the Lord worked with them, and confirmed the word by the signs that followed.
