'Labour' in the Bible

For shame hath devoured the labour of our fathers from our youth; their flocks and their herds, their sons and their daughters.

And I have given all the strength of this city, And all its labour, and all its precious things, Yea, all the treasures of the kings of Judah I do give into the hand of their enemies, And they have spoiled them, and taken them, And have brought them into Babylon.

Wherefore came I forth out of the womb to see labour and sorrow, that my days should be consumed with shame?

Thus saith the LORD of hosts; The broad walls of Babylon shall be utterly broken, and her high gates shall be burned with fire; and the people shall labour in vain, and the folk in the fire, and they shall be weary.
