After this the Lord appointed seventy others, and sent them on ahead of him, two by two, into every town and place where he himself was about to come. And he said to them, “The harvest is plentiful, but the laborers are few; pray therefore the Lord of the harvest to send out laborers into his harvest. Go your way; behold, I send you out as lambs in the midst of wolves.
–Luke 10:1-3
