'Weary' in the Bible

All things are wearisome and all words are frail;Man cannot express it.The eye is not satisfied with seeing,Nor is the ear filled with hearing.

And I applied my heart to seek and search out by wisdom concerning all that is done under the heavens: this grievous occupation hath God given to the children of men to weary themselves therewith.

The struggles of fools weary them,for they don’t know how to go to the city.
