A stone is heavy, and the sand weighty,.... As was the stone which was at the well's mouth, where Laban's flocks were watered, which could not be rolled away till all the shepherds were gathered together, Gen 29:2; and like the burdensome stone Jerusalem is compared to Zac 12:3; and as that at the sepulchre of Christ, rolled away by the angel, Mat 28:2. And sand is a very ponderous thing; difficult to be carried, as the Septuagint render it, as a bag of it is; and to which heavy afflictions are sometimes compared, Job 6:2; but a fool's wrath is heavier than them both; it cannot be removed, it rests in his bosom; it is sometimes intolerable to himself; he sinks and dies under the weight of it, as Nabal did: "wrath killeth the foolish man", Job 5:2; and it is still more intolerable to others, as Nebuchadnezzar's wrath and his fiery furnace were.
