Job 5:6,7 - Ellicott's Commentary On The Whole Bible

Although affliction.... — These two verses are confessedly very difficult. It is hard to see also the connection between sparks flying upwards and man’s being born to trouble. It seems to give better sense if we understand Eliphaz comparing man’s lot as prepared for him by God with his own pride and presumptuous ambition. Man is born to labour, but, like sparks of fire, he makes high his flight. Trouble and toil is no accidental growth, but a lot appointed by God, which would be beneficial if man did not thwart it by his own pride. They lift themselves up and soar on high like sparks of fire with daring and presumptuous conduct, and so bring on themselves condign punishment. The same word means trouble and toil, and it may be understood in the two consecutive verses in these cognate, but slightly different, senses. It would be no consolation to Job to tell him that man was born to trouble; besides, it is a sentiment more likely to proceed from the patient himself than from the spectator.
