Matthew Poole and continuators on Job 20:4

4. Knowest thou not this of old , since man was placed upon earth ?

i. e. This which I am now about to say: How canst thou, thou I say, who pretendest to such an exact and universal knowledge of men and things, be ignorant of so notorious a thing which wicked men sensibly feel, and good men diligently observe, and all men are forced to acknowledge one time or other?

i. e. From the experience of all former ages.

i. e. Since the World was made, and there were any men to observe God's Government of it.
