'Laborers' in the Bible

Then saith he unto his disciples, The harvest indeed is plenteous, but the laborers are few.

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

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

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

And when even was come, the lord of the vineyard saith unto his steward, Call the laborers, and pay them their hire, beginning from the last unto the first.
