Job 14:18,19

As the mountain falling cometh to naught, &c. As when a great mountain falls, by an earthquake or inundation, it moulders away like a fading leaf, (as the Hebrew ward signifies,) and as the rock, when, by the violence of winds or earthquakes, it is removed out of its place, and thrown down, is never re-advanced; and as the waters, by continual droppings, wear away the stones, so that they can never be made whole again; and as thou wastest away, by a great and violent inundation, the things which grow out of the dust of the earth, herbs, and fruits, and plants, which once washed away are irrecoverably lost; in like manner thou destroyest the hope of man: when man dies, all hope of his living again in this world is lost. Thus, as before he declared the hopelessness of man's restoration from death to this animal life, by way of opposition to such things as did, in a manner, rise from death to life, Job 14:7; so now he declares the same thing, by way of similitude to such things as, being once lost and gone, are past all hopes of recovery.
