A stone is heavy, and the sand weighty; but a fool's wrath is heavier than them both.

Wesley's Notes

27:3 Heavier - More grievous, being without cause, without measure, and without end.

King James Translators' Notes

heavy: Heb. heaviness

Jamieson-Fausset-Brown Bible Commentary

3. heavy-The literal sense of "heavy," applied to material subjects, illustrates its figurative, "grievous," applied to moral.

a fool's wrath-is unreasonable and excessive.

Matthew Henry's Concise Commentary

27:1 We know not what a day may bring forth. This does not forbid preparing for to-morrow, but presuming upon to-morrow. We must not put off the great work of conversion, that one thing needful. 2. There may be occasion for us to justify ourselves, but not to praise ourselves. 3,4. Those who have no command of their passions, sink under the load. 5,6. Plain and faithful rebukes are better, not only than secret hatred, but than love which compliments in sin, to the hurt of the soul. 7. The poor have a better relish of their enjoyments, and are often more thankful for them, than the rich. In like manner the proud and self-sufficient disdain the gospel; but those who hunger and thirst after righteousness, find comfort from the meanest book or sermon that testifies of Christ Jesus. 8. Every man has his proper place in society, where he may be safe and comfortable.

Matthew Henry's Whole Bible Commentary

Verses 3-4

These two verses show the intolerable mischief, 1. Of ungoverned passion. The wrath of a fool, who when he is provoked cares not what he says and does, is more grievous than a great stone or a load of sand. It lies heavily upon himself. Those who have no command of their passions do themselves even sink under the load of them. The wrath of a fool lies heavily upon those he is enraged at, to whom, in his fury, he will be in danger of doing some mischief. It is therefore our wisdom not to give provocation to a fool, but, if he be in a passion, to get out of his way. 2. Of rooted malice, which is as much worse than the former as coals of juniper are worse than a fire of thorns. Wrath (it is true) is cruel, and does many a barbarous thing, and anger is outrageous; but a secret enmity at the person of another, an envy at his prosperity, and a desire of revenge for some injury or affront, are much more mischievous. One may avoid a sudden heat, as David escaped Saul's javelin, but when it grows, as Saul's did, to a settled envy, there is no standing before it; it will pursue; it will overtake. He that grieves at the good of another will be still contriving to do him hurt, and will keep his anger for ever.
