'Labor' in the Bible

He who plants and he who waters are one [in importance and esteem, working toward the same purpose]; but each will receive his own reward according to his own labor.

Or is it only Barnabas and I who have no right to stop doing manual labor [in order to support our ministry]?

Therefore, my beloved brothers and sisters, be steadfast, immovable, always excelling in the work of the Lord [always doing your best and doing more than is needed], being continually aware that your labor [even to the point of exhaustion] in the Lord is not futile nor wasted [it is never without purpose].

They have refreshed my spirit as well as yours. So fully acknowledge such men and deeply appreciate them.
