'Seen' in the Bible

I have seen all the works that are done under the sun; and behold, all is vanity and a chasing after wind.

I have seen the burden which God has given to the sons of men to be afflicted with.

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 is a grievous evil which I have seen under the sun: wealth kept by its owner to his harm.

Behold, that which I have seen to be good and proper is for one to eat and to drink, and to enjoy good in all his labor, in which he labors under the sun, all the days of his life which God has given him; for this is his portion.

There is an evil which I have seen under the sun, and it is heavy on men:

Moreover it has not seen the sun nor known it. This has rest rather than the other.

All this have I seen in my days of vanity: there is a righteous man who perishes in his righteousness, and there is a wicked man who lives long in his evildoing.

All this have I seen, and applied my mind to every work that is done under the sun. There is a time in which one man has power over another to his hurt.

I have also seen wisdom under the sun in this way, and it seemed great to me.

There is an evil which I have seen under the sun, the sort of error which proceeds from the ruler.

I have seen servants on horses, and princes walking like servants on the earth.
