'Found' in the Bible

I have seen all the things that are done under the sun and have found everything to be futile, a pursuit of the wind.

I thought to myself, "Come now, I will try self-indulgent pleasure to see if it is worthwhile." But I found that it also is futile.

When I considered all that I had accomplished and what I had labored to achieve, I found everything to be futile and a pursuit of the wind. There was nothing to be gained under the sun.

and I found more bitter than death the woman whose heart is nets and snares, and whose hands are bands: whoso pleaseth God shall escape from her; but the sinner shall be caught by her.

Behold, this have I found, saith the preacher, counting one by one, to find out the account:

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

Lo, this only have I found, that God hath made man upright; but they have sought out many inventions.

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.
