'Satisfied' in the Bible

All things are wearisome and all words are frail;Man cannot express it.The eye is not satisfied with seeing,Nor is the ear filled with hearing.

There was a certain man—without a dependent, having neither a child nor a brother, yet there was no end to all his labor. Indeed, his eyes were not satisfied with riches and he never asked, “For whom do I labor and deprive myself of pleasure?” This too is vanity (a wisp of smoke, self-conceit); yes, it is a painful effort and an unhappy task.

He who loves money will not be satisfied with money, nor he who loves abundance with its gain. This too is vanity (emptiness).

All the labor of man is for his mouth [for self-preservation and enjoyment], and yet the desire [of his soul] is not satisfied.
