'Labor' in the Bible

Isn’t mankind consigned to forced labor on earth?Are not his days like those of a hired hand?

Since I will be found guilty,why should I labor in vain?

He must return the fruit of his labor without consuming it;he doesn’t enjoy the profits from his trading.

Do you know when mountain goats give birth?Have you watched the deer in labor?

She treats her young harshly, as if they were not her own,with no fear that her labor may have been in vain.
