16 ¶ When I applied mine │ Whence it results, that having heart to know wisdom, and to │ set my heart to know wisdom, see the business that is done │ and to observe with regard to upon the earth: (for also │ the uncertainty which is _there is that_ neither day │ suffered upon earth (for indeed, nor night seeth sleep with his │ by day and by night also, _rest_ eyes:) │ does no human eye behold)―― (16.) =As then I have given with respect to my heart= (with את) =to the knowledge of wisdom, and to the appearances= (וְלִרְאוֹת; this infinitive with וְ is peculiar to Ecclesiastes――occurs chapters iii. 18, v. 17, and here; see the peculiar shade of meaning given by the conjunction) =with respect to the anxiety= (see chapter i. 13; generic with את, of which, however, the LXX. take no special notice) =which is done on earth= (but we must write ‘endured upon earth’ to express the meaning, which amounts to this, ‘As, then, I have given my heart to the knowledge of wisdom, _i.e._ a scientific knowledge, with regard to the spectacle of that anxious uncertainty which is suffered on the earth’), for =also by day and by night sleep= (the Masorets with great taste put ‘sleep’ in a clausule by itself) =with his eyes he is not seeing= (_i.e._ this uncertainty is incessant). 17 Then I beheld all the │ so I perceive, with respect to work of God, that a man cannot │ the whole working of the find out the work that is done │ Almighty, how impossible is it under the sun: because though │ for humanity to discover the a man labour to seek _it_ out, │ working out of anything with yet he shall not find _it_; │ respect to what is done within yea farther, though a wise │ this work-day world.
