'Yet' in the Bible

Yet when I considered all the effort which I expended and the toil with which I toiled to do, then behold, "Everything [is] vanity and chasing wind! There is nothing profitable under the sun!"

{The wise man can see where he is walking}, but the fool walks in darkness. Yet I also realized that both of them suffer the same fate.

And who knows [whether] he will be wise or foolish? Yet he will exercise control of all [the fruit of] my toil with which I toiled wisely under the sun. This also [is] vanity!

He has made everything suitable in its time. He also has put {the past} in their hearts, yet no one can grasp what God does from the beginning to the end.

But better [off] than both of them is the one who has not yet been born and has not seen the evil deeds that are done under the sun.

Sometimes a man is all alone with no companion; he also has neither son nor brother. Yet there is no end to all his toil, and his eye is not satisfied with wealth. [He laments,] "For whom am I toiling and depriving {myself} of pleasure?" This also [is] vanity--it is an unhappy business!

There is no end to all the people, to all who were before him. Yet the later generation will not rejoice in him, for this also [is] vanity and chasing wind!

God gives a man wealth, possessions, and honor, so that he lacks nothing his heart desires; yet God does not enable him to enjoy it--instead someone else ends up enjoying it. This [is] vanity--indeed, it [is] a grievous ill!

He has neither seen nor known the sun, yet he has more rest than him.

All of a man's toil [is] for his mouth-- yet his appetite is never satisfied.

Although the sinner does evil a hundred times and prolongs his life, yet I also know that it will be good for those who fear God--because they fear {his presence}.

So I concluded that wisdom [is] better than might, yet the wisdom of the poor is despised, and his words are not heard.
