'Laboring' in the Bible

The appetite of the laboring man laboreth for him; For his mouth urgeth him thereto .

The sleep of a laboring man is sweet, whether he eat little or much; but the fulness of the rich will not suffer him to sleep.

In all things I gave you an example, that so laboring ye ought to help the weak, and to remember the words of the Lord Jesus, that he himself said, It is more blessed to give than to receive.
