'Works' in the Bible

I saw all the works that are done under the sun. Look! Everything [is] vanity and chasing wind.

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 people in it. A great king came and besieged it, building great siege works against it.
