Jamieson, Fausset and Brown on Jeremiah 26:20

20. As the flight and capture of Urijah must have occupied some time, "the beginning of the reign of Jehoiakim" (Jr 26:1) must not mean the very beginning, but the second or third year of his eleven years' reign.

And ... also--perhaps connected with Jr 26:24, as the comment of the writer, not the continuation of the speech of the elders: "And although also a man that prophesied ... Urijah ... (proving how great was the danger in which Jeremiah stood, and how wonderful the providence of God in preserving him), nevertheless the hand of Ahikam," &c. [Glassius]. The context, however, implies rather that the words are the continuation of the previous speech of the elders. They adduce another instance besides that of Micah, though of a different kind, namely, that of Urijah: he suffered for his prophecies, but they imply, though they do not venture to express it, that thereby sin has been added to sin, and that it has done no good to Jehoiakim, for that the notorious condition of the state at this time shows that a heavier vengeance is impending if they persevere in such acts of violence [Calvin].
