'Labourers' in the Bible

Then saith he unto his disciples, The harvest truly is plenteous, but the labourers are few;

Pray ye therefore the Lord of the harvest, that he will send forth labourers into his harvest.

For the kingdom of heaven is like unto a man that is an householder, which went out early in the morning to hire labourers into his vineyard.

And when he had agreed with the labourers for a penny a day, he sent them into his vineyard.

So when even was come, the lord of the vineyard saith unto his steward, Call the labourers, and give them their hire, beginning from the last unto the first.

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.

For we are labourers together with God: ye are God's husbandry, ye are God's building.

Behold, the hire of the labourers who have reaped down your fields, which is of you kept back by fraud, crieth: and the cries of them which have reaped are entered into the ears of the Lord of sabaoth.
