Jamieson-Fausset-Brown Bible Commentary

12. The second part of the chapter: the effect which the presence of a few righteous persons was to have on the purposes of God (compare Ge 18:24-32). God had told Jeremiah that the guilt of Judah was too great to be pardoned even for the intercession of Moses and Samuel (Ps 99:6; Jer 14:2; 15:1), which had prevailed formerly (Ex 32:11-14; Nu 14:13-20; 1Sa 7:8-12), implying the extraordinary heinousness of their guilt, since in ordinary cases "the effectual fervent prayer of a righteous man (for others) availeth much" (Jas 5:16). Ezekiel supplements Jeremiah by adding that not only those two once successful intercessors, but not even the three pre-eminently righteous men, Noah, Daniel, and Job, could stay God's judgments by their righteousness.

Matthew Henry's Concise Commentary

14:12-23 National sins bring national judgments. Though sinners escape one judgment, another is waiting for them. When God's professing people rebel against him, they may justly expect all his judgments. The faith, obedience, and prayers of Noah prevailed to the saving of his house, but not of the old world. Job's sacrifice and prayer in behalf of his friends were accepted, and Daniel had prevailed for the saving his companions and the wise men of Babylon. But a people that had filled the measure of their sins, was not to expect to escape for the sake of any righteous men living among them; not even of the most eminent saints, who could be accepted in their own case only through the sufferings and righteousness of Christ. Yet even when God makes the greatest desolations by his judgments, he saves some to be monuments of his mercy. In firm belief that we shall approve the whole of God's dealings with ourselves, and with all mankind, let us silence all rebellious murmurs and objections.
