What was the mission of the seventy disciples - JSS2 Christian Religious Studies Call of the disciples II Question

Jesus said the seventy should pray to the Lord of the harvest to send more labourers into his harvest. He was sending them out as lambs in the midst of wolves. They should carry no purse, no bag, no sandals, and greet no one on the road. When they enter a house they should pray: “Peace be to this house.”
