'Work' in the Bible

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

He hath made everything beautiful in its time: also he hath set eternity in their heart, yet so that man cannot find out the work that God hath 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.

yea, better than them both did I esteem him that hath not yet been, who hath not seen the evil work that is done under the sun.

Then I saw all labor and every skilful work, that for this a man is envied of his neighbor. This also is vanity and a striving after wind.

Suffer not thy mouth to cause thy flesh to sin; neither say thou before the angel, that is was an error: wherefore should God be angry at thy voice, and destroy the work of thy hands?

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

All this have I seen, and applied my heart unto every work that is done under the sun: there is a time wherein one man hath 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 upon the earth, that there are righteous men unto whom it happeneth according to the work of the wicked; again, there are wicked men to whom it happeneth according to the work of the righteous: I said that this also is vanity.

then I beheld all the work of God, that man cannot find out the work that is done under the sun: because however much a man labor to seek it out, yet he shall not find it; yea moreover, though a wise man think to know it, yet shall he not be able to find it.

Whatsoever thy hand findeth to do, do it with thy might; for there is no work, nor device, nor knowledge, nor wisdom, in Sheol, whither thou goest.

As thou knowest not what is the way of the wind, nor how the bones do grow in the womb of her that is with child; even so thou knowest not the work of God who doeth all.

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