Luke 10:2; Luke 10:7; Luke 13:27

2 Therefore said he unto 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.
7 And in the same house remain , eating and drinking such things as they give: for the labourer is worthy of his hire. Go not from house to house.
27 But he shall say , I tell you, I know you not whence ye are ; depart from me, all ye workers of iniquity.
