'Yet' in the Bible

All the rivers run into the sea, yet the sea is not full; unto the place whither the rivers go, thither they go 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 on folly, till I might see what it was good for the sons of men that they should do under heaven all the days of their life.

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

And who knoweth whether he will be a wise man or a fool? yet will he have rule over all my labor wherein I have labored, and wherein I have showed myself wise under the sun. This also is vanity.

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

He hath made everything beautiful in its time: also he hath set eternity in their heart, yet so that man cannot find out the work that God hath done from the beginning even to the end.

Wherefore I praised the dead that have been long dead more than the living that are yet alive;

yea, better than them both did I esteem him that hath not yet been, who hath not seen the evil work that is done under the sun.

There is one that is alone, and he hath not a second; yea, he hath neither son nor brother; yet is there no end of all his labor, neither are his eyes satisfied with riches. For whom then,'saith he , do I labor, and deprive my soul of good? This also is vanity, yea, it is a sore travail.

There was no end of all the people, even of all them over whom he was: yet they that come after shall not rejoice in him. Surely this also is vanity and a striving after wind.

a man to whom God giveth riches, wealth, and honor, so that he lacketh nothing for his soul of all that he desireth, yet God giveth him not power to eat thereof, but an alien eateth it; this is vanity, and it is an evil disease.

yea, though he live a thousand years twice told, and yet enjoy no good, do not all go to one place?

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

Though a sinner do evil a hundred times, and prolong his days , yet surely I know that it shall be well with them that fear God, that fear before him:

then I beheld all the work of God, that man cannot find out the work that is done under the sun: because however much a man labor to seek it out, yet he shall not find it; yea moreover, though a wise man think to know it, yet shall he not 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 happeneth to them all.

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

A fool also multiplieth words: yet man knoweth not what shall be; and that which shall be after him, who can tell him?
