Bible Verses About Travellers: Saluted no man by the way

Then he said to Gehazi, Gird up thy loins, and take my staff in thy hand, and go thy way: if thou meet any man, salute him not; and if any salute thee, answer him not again: and lay my staff upon the face of the child.

Carry no purse, no wallet, no shoes; and salute no man on the way.
