Luke 9:4

Then he called his twelve disciples together, and gave them power and authority over all devils, and to cure diseases.

And he sent them to preach the kingdom of God, and to heal the sick.

And he said unto them, Take nothing for your journey, neither staves, nor scrip, neither bread, neither money; neither have two coats apiece.

And whosoever will not receive you, when ye go out of that city, shake off the very dust from your feet for a testimony against them.
