Job 28:23 - Albert Barnes' Notes on the Bible

God understandeth the way thereof - These are doubtless the words of Job. The meaning is, that the reason of the divine dispensations could be known only to God himself. He had given no clew by which man could discover this. He might carry his investigations far into the regions of science; he could penetrate the earth, and look on the stars, but still all his investigations fell short of disclosing the reasons of the divine dispensations. The secret was lodged in his bosom, and he only could communicate it where and when he pleased. It may be added here, that this is as true now as it was in the time of Job. Man has carried the investigations of science almost infinitely further than he had then, but still by the investigations of science he has by no means superseded the necessity of revelation, or shed light on the great questions that have, in all ages, so much perplexed the race. It is only by direct communication, by his word and by his Spirit, that man can be made to understand the reason of the divine doings, and nothing is better established by the course of events than the truth on which Job here so much insists, that science cannot answer the questions of so much interest to man about the divine government.
