Luke 9:4 Meaning

2And he sent them to preach the kingdom of God, and to heal the sick.

3And he said unto them, Take nothing for your journey, neither staves, nor scrip, neither bread, neither money; neither have two coats apiece.

4And whatsoever house ye enter into, there abide, and thence depart.

5And 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.

6And they departed, and went through the towns, preaching the gospel, and healing every where.
