Luke 10:1-3

1After these things the Lord appointed other seventy also, and sent them two and two before his face into every city and place, where he himself would come.

2Therefore said he to them, The harvest truly is great, but the labourers are few: pray ye therefore the Lord of the harvest, that he would send forth labourers into his harvest.

3Go your ways: behold, I send you forth as lambs among wolves.
