'Work' in the Bible

[The Lord replied,] “Look among the nations! See!Be astonished! Wonder!For I am doing something in your days—You would not believe it if you were told.

“Is it not indeed from the Lord of hostsThat peoples labor [only] for the fire [that will destroy their work],And nations grow weary for nothing [that is, things which have no lasting value]?

O Lord, I have heard the report about You and I fear.O Lord, revive Your work in the midst of the years,In the midst of the years make it known;In wrath [earnestly] remember compassion and love.
