'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.

And who knoweth whether he will be a wise man or a fool? yet shall he have rule over all my labour at which I have laboured, and wherein I have been wise under the sun. This also is vanity.

Then I praised the dead who are already dead more than the living who are yet alive;

and more fortunate than both is he who hath not yet been, who hath not seen the evil work that is done under the sun.

There is one alone and without a second; also he hath neither son nor brother: yet is there no end of all his labour, neither is his eye satisfied with riches, and he saith not, For whom then am I labouring, and depriving my soul of good? This also is vanity and a grievous occupation.

one to whom God giveth riches, wealth, and honour, and he wanteth nothing for his soul of all that he desireth, yet God giveth him not power to eat thereof, but a stranger eateth it: this is vanity, and a sore evil.

Yea, though he live twice a thousand years, yet hath he seen no good: do not all go to one place?

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

which my soul yet seeketh, and I have not found: one man among a thousand have I found, but a woman among all those have I not found.

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

then I saw that all is the work of God, and that man cannot find out the work that is done under the sun: because however man may labour to seek it out, yet doth he not find it; and even, if a wise man think to know it, he shall not be able to find it out.

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 the intelligent, nor yet favour to men of knowledge; but time and chance happeneth to them all.

And the fool multiplieth words: yet man knoweth not what shall be; and what shall be after him, who will tell him?

but if a man live many years, and rejoice in them all, yet let him remember the days of darkness; for they shall be many: all that cometh is vanity.
