on Job 4 :20
They are destroyed from morning to evening - In almost every moment of time some human being comes into the world, and some one departs from it. Thus are they "destroyed from morning to evening."
They perish for ever - יאבדו yobedu; peribunt, they pass by; they go out of sight; they moulder with the dust, and are soon forgotten. Who regards the past generation now among the dead? Isaiah has a similar thought, Isaiah 57:1 : "The righteous perisheth, and No Man Layeth It to Heart: and merciful men are taken away, none considering that the righteous is taken away from the evil to come." Some think that Isaiah borrowed from Job; this will appear possible when it has been proved, which has never yet been done, that the writer of this book flourished before Isaiah. If, however, he borrowed the above thought, it must be allowed that it has been wondrously improved by coming through his hands.
on Job 4 :20
They are destroyed from morning to evening - Margin, "beaten in pieces." This is nearer to the Hebrew. The phrase "from morning to evening" means between the morning and the evening; that is, they live scarcely a single day; see the notes at Isaiah 38:12. The idea is, not the continuance of the work of destruction from morning to evening; but that man's life is excecdingly short, so short that he scarce seems to live from morning to night. What a beautiful expression, and how true! How little qualified is such a being to sit in judgment on the doings of the Most High!
They perish forever - Without being restored to life. They pass away, and nothing is ever seen of them again!
Without any regarding it - Without its being noticed. How strikingly true is this! What a narrow circle is affected by the death of a man, and how soon does even that circle cease to be affected! A few relatives and friends feel it and weep over the loss; but the mass of men are unconcerned. It is like taking a grain of sand from the sea-shore, or a drop of water from the ocean. There is indeed one less, but the place is soon supplied, and the ocean rolls on its tumultuous billows as though none had been taken away. So with human life. The affairs of people will roll on; the world will be as busy, and active, and thoughtless as though we had not been; and soon, O how painfully soon to human pride, will our names be forgotten! The circle of friends will cease to weep, and then cease to remember us. The last memorial that we lived, will be gone. The house that we built, the bed on which we slept, the counting-room that we occupied, the monuments that we raised, the books that we made, the stone that we directed to be placed over our graves, will all be gone; and the last memento that we ever lived, will have faded away! How vain is man! How vain is pride! How foolish is ambition! How important the announcement that there is another world, where we may live on forever!
on Job 4 :20
4:20 Destroyed - All the day long, there is not a moment wherein man is not sinking towards death and corruption. Perish - In reference to this present worldly life, which when once lost is never recovered. Regarding - Heb. without putting the heart to it, this is so common a thing for all men, though never so high and great, to perish in this manner, that no man heeds it, but passes it by as a general accident not worthy of observation.
