'Labor' in the Bible

Now the one who plants and the one who waters are one, but each one will receive his own reward according to his own labor.

So then, my dear brothers, be steadfast, immovable, always abounding in the work of the Lord, [because you] know that your labor is not [in] vain in the Lord.

that you also be subject to such people, and to all those who work together and labor.
