In Luke 10 we read how Jesus paired up 72 of his followers and gave them some specific instructions. He told them:

  1. Ask the “chief farmer” to send workers out into the “harvest”, then go.
  2. Don’t take extra stuff, whether a purse, bag or sandals. Don’t spend time chatting to everyone passing by.
  3. If you find people of peace and hospitality, bless them.
  4. Eat whatever you’re given.
  5. Heal their sick people and tell them the kingdom of God has arrived in town.
  6. If people reject you, move on.

Stories of similar excursions are told in Matthew 10, Mark 6 and Luke 9.
