Verses 21-23. - Then follows a proverb concerning four things which are intolerable, examples of incongruous associations or positions - two in the case of men, two in the case of women. Verse 21. - For three things the earth is disquieted; better, under three things the earth doth tremble, as if oppressed by an overwhelming borden. The form of expression does not allow us to think of an earthquake. "The earth" is equivalent to "the inhabitants thereof." And for four which it cannot bear; or, under four it cannot stand (comp. Amos 7:10). These four evils destroy the comfort of social life, uproot the bonds of society, and endanger the safety of a nation.

30:10 Slander not a servant to his master, accuse him not in small matters, to make mischief. 11-14. In every age there are monsters of ingratitude who ill-treat their parents. Many persuade themselves they are holy persons, whose hearts are full of sin, and who practise secret wickedness. There are others whose lofty pride is manifest. There have also been cruel monsters in every age. 15-17. Cruelty and covetousness are two daughters of the horseleech, that still cry, Give, give, and they are continually uneasy to themselves. Four things never are satisfied, to which these devourers are compared. Those are never rich that are always coveting. And many who have come to a bad end, have owned that their wicked courses began by despising their parents' authority. 18-20. Four things cannot be fully known. The kingdom of nature is full of marvels. The fourth is a mystery of iniquity; the cursed arts by which a vile seducer gains the affections of a female; and the arts which a vile woman uses to conceal her wickedness. 21-23 Four sorts of persons are very troublesome. Men of low origin and base spirit, who, getting authority, become tyrants. Foolish and violent men indulging in excesses. A woman of a contentious spirit and vicious habits. A servant who has obtained undue influence. Let those whom Providence has advanced from low beginnings, carefully watch against that sin which most easily besets them.For three things the earth is disquieted,.... The inhabitants of it are made very uneasy;

and for four which it cannot bear; they are a load and burden upon it, and are intolerable to those that dwell on it, and make them very uncomfortable.
