'Works' in the Bible

I have seen all the works which are done under the sun; all is to no purpose, and desire for wind.

I undertook great works, building myself houses and planting vine-gardens.

Then I saw all the works which my hands had made, and everything I had been working to do; and I saw that all was to no purpose and desire for wind, and there was no profit under the sun.

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.

All this I took to heart, and my heart saw it all: that the upright and the wise and their works are in the hand of God; and men may not be certain if it will be love or hate; all is to no purpose before them.

Come, take your bread with joy, and your wine with a glad heart. God has taken pleasure in your works.

There was a little town and the number of its men was small, and there came a great king against it and made an attack on it, building works of war round about it.

As you have no knowledge of the way of the wind, or of the growth of the bones in the body of her who is with child, even so you have no knowledge of the works of God who has made all.
