'Dead' in the Bible

So I congratulated and thought more fortunate are those who are already dead than the living who are still living.

Even if the other man lives a thousand years twice over and yet has seen no good and experienced no enjoyment—do not both go to one place [the grave]?”

This evil is in all that is done under the sun, that one fate comes to all. Also, the hearts of the sons of men are full of evil, and madness is in their hearts while they live, and afterwards they go to the dead.

[There is no exemption,] but whoever is joined with all the living, has hope; surely a live dog is better than a dead lion.

For the living know that they will die; but the dead know nothing, and they no longer have a reward [here], for the memory of them is forgotten.

Whatever your hand finds to do, do it with all your might; for there is no activity or planning or knowledge or wisdom in Sheol (the nether world, the place of the dead) where you are going.

Dead flies make the oil of the perfumer give off a foul odor; so a little foolishness [in one who is esteemed] outweighs wisdom and honor.
