"After this the Lord appointed seventy-two others and sent them two by two ahead of him to every town and place where he was about to go. He told them, "The harvest is plentiful, but the workers are few. Ask the Lord of the harvest, therefore, to send out workers into his harvest field. Go! I am sending you out like lambs among wolves. Do not take a purse or bag or sandals; and do not greet anyone on the road." (Luke 10:1-4)
