Matthew Poole and continuators on Job 5:7

7. Yet man is born unto trouble , as the sparks fly upward .

i. e. He is so commonly exposed to many and various troubles, as if he were born to no other end: Affliction is become in some sort natural and proper to man, and it is together with sin transmitted from parents to Children, as their most certain, and constant inheritance; God having allotted this portion to mankind for their sins. And therefore thou takest a wrong course in complaining so bitterly of that which thou shouldest patiently bear as the common lot of mankind, and thy right method is to seek unto God who inflicts it, and who onely can remove it.

i. e. As naturally, and as generally, as the sparks of fire fly upward, which do so universally and conssantly. Heb. and the sparks &c. But the particle and is oft used comparatively for as, as Ch. 12. 11. & 14. 12. & 34. 3. Prov. 25. 24. Mark. 9. 49.

Marginal references: Or, labour.; Heb. the sons of the burning coals lift up to fly.
