Luke 9: 1 - 6
1 And he called the twelve together and gave them power and authority over all demons and to cure diseases,
2 and he sent them out to preach the kingdom of God and to heal.
3 And he said to them, "Take nothing for your journey, no staff, nor bag, nor bread, nor money; and do not have two tunics.
4 And whatever house you enter, stay there, and from there depart.
5 And wherever they do not receive you, when you leave that town shake off the dust from your feet as a testimony against them."
6 And they departed and went through the villages, preaching the gospel and healing everywhere.
