'Seen' in the Bible

I have seen all the works that are done under the sun, and behold, all is vanity and pursuit of the wind.

I communed with mine own heart, saying, Lo, I have become great and have acquired wisdom more than all they that have been before me over Jerusalem; and my heart hath seen much of wisdom and knowledge.

I have seen the travail that God hath given to the sons of men to toil in.

And I have seen that there is nothing better than that man should rejoice in his own works; for that is his portion; for who shall bring him to see what shall be after him?

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 a grievous evil that I have seen under the sun: riches kept for the owners thereof to their hurt;

Behold what I have seen good and comely: it is to eat and to drink, and to enjoy good in all his labour wherewith man laboureth under the sun, all the days of his life which God hath given him: for that is his portion.

There is an evil that I have seen under the sun, and it is frequent among men:

moreover it hath not seen nor known the sun: this hath rest rather than the other.

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

All this have I seen in the days of my vanity: there is a righteous man that perisheth by his righteousness, and there is a wicked man that prolongeth his days by his wickedness.

All this have I seen, and applied my heart unto every work that is done under the sun: there is a time when man ruleth man to his hurt.

And I have also seen the wicked buried and going away; and such as had acted rightly went from the holy place, and were forgotten in the city. This also is vanity.

This also have I seen as wisdom under the sun, and it was great unto me.

There is an evil that I have seen under the sun, as an error that proceedeth from the ruler:

I have seen servants upon horses, and princes walking as servants upon the earth.
