'Works' in the Bible

I have seen all the works that are done under the sun; and, behold, all is vanity and vexation of spirit.

I made me great works; I builded me houses; I planted me vineyards:

Then I looked on all the works that my hands had wrought, and on the labour that I had laboured to do: and, behold, all was vanity and vexation of spirit, and there was no profit under the sun.

What profit has he who works in that in which he labors?

He has made everything right in its time; but he has made their hearts without knowledge, so that man is unable to see the works of God, from the first to the last.

I know that all God does will last forever; there is no adding to it or taking from it. God works so that people will be in awe of Him.

Wherefore I perceive that there is nothing better, than that a man should rejoice in his own works; for that is his portion: for who shall bring him to see what shall be after him?

Every person works for his own self-interests, but his desires remain unsatisfied.

I saw all of it as the activity of God. Frankly, a human being cannot understand what happens on earth, because however hard a man works to discover it, he will not find out. Despite what he thinks he knows, he will not be able to figure it out.

For all this I considered in my heart even to declare all this, that the righteous, and the wise, and their works, are in the hand of God: no man knoweth either love or hatred by all that is before them.

Go thy way, eat thy bread with joy, and drink thy wine with a merry heart; for God now accepteth thy works.

Whatever your hand finds to do--do [it] with [all] your might; for in Sheol--where you are going--no one works, plans, knows, or thinks about anything.

There was a small city with few men in it. A great king came against it, surrounded it, and built large siege works against it.

As thou knowest not what is the way of the spirit, nor how the bones do grow in the womb of her that is with child: even so thou knowest not the works of God who maketh all.
