'Work' in the Bible

"Look among the nations, watch, and wonder marvelously; for I am working a work in your days, which you will not believe though it is told you.

Yahweh, I have heard of your fame. I stand in awe of your deeds, Yahweh. Renew your work in the midst of the years. In the midst of the years make it known. In wrath, you remember mercy.
