'Work' in the Bible

So I hated life, because the work that is worked under the sun was grievous to me; for all is vanity and a chasing after wind.

He has made everything beautiful in its time. He has also set eternity in their hearts, yet so that man can't find out the work that God has done from the beginning even to the end.

I said in my heart, "God will judge the righteous and the wicked; for there is a time there for every purpose and for every work."

Yes, better than them both is him who has not yet been, who has not seen the evil work that is done under the sun.

Don't allow your mouth to lead you into sin. Don't protest before the messenger that this was a mistake. Why should God be angry at your voice, and destroy the work of your hands?

Consider the work of God, for who can make that straight, which he has made crooked?

All this have I seen, and applied my mind to every work that is done under the sun. There is a time in which one man has power over another to his hurt.

Because sentence against an evil work is not executed speedily, therefore the heart of the sons of men is fully set in them to do evil.

There is a vanity which is done on the earth, that there are righteous men to whom it happens according to the work of the wicked. Again, there are wicked men to whom it happens according to the work of the righteous. I said that this also is vanity.

then I saw all the work of God, that man can't find out the work that is done under the sun, because however much a man labors to seek it out, yet he won't find it. Yes even though a wise man thinks he can comprehend it, he won't be able to find it.

Whatever your hand finds to do, do it with your might; for there is no work, nor device, nor knowledge, nor wisdom, in Sheol, where you are going.

As you don't know what is the way of the wind, nor how the bones grow in the womb of her who is with child; even so you don't know the work of God who does all.

For God will bring every work into judgment, with every hidden thing, whether it is good, or whether it is evil.
