'Labour' in the Bible

Now he that planteth and he that watereth are one: and every man shall receive his own reward according to his own labour.

And labour, working with our own hands: being reviled, we bless; being persecuted, we suffer it:

Therefore, my beloved brethren, be ye stedfast, unmoveable, always abounding in the work of the Lord, forasmuch as ye know that your labour is not in vain in the Lord.
