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.

Luke 10:18-20

18 He replied, “I saw Satan fall like lightning from heaven. 19 I have given you authority to trample on snakes and scorpions and to overcome all the power of the enemy; nothing will harm you. 20 However, do not rejoice that the spirits submit to you, but rejoice that your names are written in heaven.”

Matthew 9:35-38

35 And Jesus went throughout all the cities and villages, teaching in their synagogues and proclaiming the gospel of the kingdom and healing every disease and every affliction. 36 When he saw the crowds, he had compassion for them, because they were harassed and helpless, like sheep without a shepherd. 37 Then he said to his disciples, “The harvest is plentiful, but the laborers are few; 38 therefore pray earnestly to the Lord of the harvest to send out laborers into his harvest.”
