'Laboring' in the Bible

The appetite of the laboring man labors for him; for his mouth urges him on.

The sleep of a laboring man is sweet, whether he eats little or much; but the abundance of the rich will not allow him to sleep.

In all things I gave you an example, that so laboring you 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.'"

She was with child. She cried out in pain, laboring to give birth.
