Job 36:28 - Albert Barnes' Notes on the Bible

Upon man abundantly - That is, upon many people. The clouds having received the ascending vapor, retain it, and pour it down copiously for the use of man. The arrangement, to the eye even of one who did not understand the scientific principles by which it is done, is beautiful and wonderful; the beauty and wonder are increased when the laws by which it is accomplished are understood. Elihu does not attempt to explain the mode by which this is done. The fact was probably all that was then understood, and that was sufficient for his purpose. The Septuagint has given a translation of this verse which cannot be well accounted for, and which is certainly very unlike the original. It is, “But when the clouds east a shade over the dumb creation, he impresseth a care on beasts, and they know the order for retiring to rest - κοίτης τάξιν koitēs taxin. At all these things is not their understanding confounded? And is not thy heart starting from thy body?”
