'Yet' in the Bible

All the rivers run into the sea, yet the sea is not full. To the place where the rivers flow, there they flow again.

I searched in my heart how to cheer my flesh with wine, my heart yet guiding me with wisdom, and how to lay hold of folly, until I might see what it was good for the sons of men that they should do under heaven all the days of their lives.

The wise man's eyes are in his head, and the fool walks in darkness -- and yet I perceived that one event happens to them all.

Who knows whether he will be a wise man or a fool? Yet he will have rule over all of my labor in which I have labored, and in which I have shown myself wise under the sun. This also is vanity.

For there is a man whose labor is with wisdom, with knowledge, and with skillfulness; yet he shall leave it for his portion to a man who has not labored for it. This also is vanity and a great evil.

He has made everything beautiful in its time. He has also set eternity in their hearts, yet so that man can't find out the work that God has done from the beginning even to the end.

Therefore I praised the dead who have been long dead more than the living who are yet alive.

Yes, better than them both is him who has not yet been, who has not seen the evil work that is done under the sun.

There was no end of all the people, even of all them over whom he was -- yet those who come after shall not rejoice in him. Surely this also is vanity and a chasing after wind.

a man to whom God gives riches, wealth, and honor, so that he lacks nothing for his soul of all that he desires, yet God gives him no power to eat of it, but an alien eats it. This is vanity, and it is an evil disease.

Yes, though he live a thousand years twice told, and yet fails to enjoy good, don't all go to one place?

All the labor of man is for his mouth, and yet the appetite is not filled.

Though a sinner commits crimes a hundred times, and lives long, yet surely I know that it will be better with those who fear God, who are reverent before him.

then I saw all the work of God, that man can't find out the work that is done under the sun, because however much a man labors to seek it out, yet he won't find it. Yes even though a wise man thinks he can comprehend it, he won't be able to find it.

I returned, and saw under the sun, that the race is not to the swift, nor the battle to the strong, neither yet bread to the wise, nor yet riches to men of understanding, nor yet favor to men of skill; but time and chance happen to them all.

Now a poor wise man was found in it, and he by his wisdom delivered the city; yet no man remembered that same poor man.
