Let there be none to extend mercy unto him: neither let there be any to favour his fatherless children.

May there be none to help him: nor none to pity his fatherless offspring.

Let there be none to extend kindness unto him, neither let there be any to favour his fatherless children;

Let there be none to extend mercy unto him; neither let there be any to have pity on his fatherless children.

Let there be none to extend mercy to him: neither let there be any to favor his fatherless children.

He hath none to extend kindness, Nor is there one showing favour to his orphans.

Let no man have pity on him, or give help to his children when he is dead.

Let there be none to extend kindness unto him; Neither let there be any to be gracious unto his fatherless children.

Let there be none prolonging mercy to him. To continue to show humanity and mercy is, according to the Hebrew idiom, equivalent to constant and successive acts of kindness; and it also sometimes denotes pity, or the being moved to sympathy, when, through the lapse of years, anger is appeased, and even one's calamity melts the heart of the man who bore hatred towards him. Accordingly, there are some who understand this clause to mean, that there will be none to show kindness to his offspring; which interpretation is in conformity with the next clause of the verse. David, however, includes also the wicked man himself along with his children; as if he should say, Though he visibly pine away under such calamities, and these descend to his children, yet let no one show pity towards them. We are aware it not unfrequently happens, that the long-continued misfortune of an enemy either excites the sympathy of men of savage dispositions, or else makes them forget all their hatred and malevolence. But in this part of the psalm, David expresses a desire that his enemy and all his posterity may be so hated and detested, that the people may never be wearied with beholding the calamities which they endure, but may become so familiarised with the spectacle, as if their hearts were of iron. At the same time, let it be remarked, that David is not rashly excited by any personal anguish to speak in this manner, but that it is as God's messenger he declares the punishment which was impending over the ungodly. And verily the law accounts it as one of the judgments of God, his hardening men's hearts, so that they who have been passionately and unmercifully cruel, should find no sympathy, Deuteronomy 2:30. It is just that the same measure which they have used towards others, should also be meted out to themselves.

Let there be none to extend mercy unto him - Let him find compassion and sympathy in no one. When he suffers, let him be left to bear it alone. Let there be none found to shed a tear of compassion over him, or to relieve him. Literally, "Let there be no one to draw out kindness to him."
Neither let there be any to favor his fatherless children - To show them mercy or kindness. See the notes at Psalm 109:10.

Let there be none to extend mercy unto him,.... No pity is ever expressed at hearing or reading the sad case of Judas; and though the Jews were pitied of those that carried them captive to Babylon, Psalm 106:46, yet, in their last destruction by the Romans, no mercy was shown them; the wrath of God and man came upon them to the uttermost, 1-Thessalonians 2:16.
Neither let there be any to favour his fatherless children: to bestow any benefit upon them; to relieve their wants, nor to protect their persons; no more respect shown them than to their father, being shunned and hated for their father's sake.
