'Things' in the Bible

All things are wearisome;man is unable to speak.The eye is not satisfied by seeingor the ear filled with hearing.

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

When good things increase, the ones who consume them multiply; what, then, is the profit to the owner, except to gaze at them with his eyes?

A man may father a hundred children and live many years. No matter how long he lives, if he is not satisfied by good things and does not even have a proper burial, I say that a stillborn child is better off than he.

I turned my thoughts to know, explore, and seek wisdom and an explanation for things, and to know that wickedness is stupidity and folly is madness.

Rejoice, young man, while you are young,and let your heart be glad in the days of your youth.And walk in the ways of your heartand in the sight of your eyes;but know that for all of these things God will bring you to judgment.
