Matthew Poole and continuators on Ecclesiastes 1:3

3 What profit hath a man of all his labour which he taketh under the Sun .

Or, as others render it, What remainder? What real and abiding benefit hath a Man by it? None at all. All is unprofitable as to the attainment of that happiness which Solomon here is, and all men in the World are enquiring after.

Heb. his toilsom labour, both of Body and Mind in the pursuit of Riches, or Pleasures, or other earthly things.

In all sublunary or worldly matters, which are usually transacted in the Day time, or by the light of the Sun. By this restriction he implies that that profit and happiness which in vain is sought for in this lower World is really and onely to be found in Heavenly places and things.
