Albert Barnes Commentary Jeremiah 36:30

"Therefore thus saith Jehovah concerning Jehoiakim king of Judah: He shall have none to sit upon the throne of David; and his dead body shall be cast out in the day to the heat, and in the night to the frost." — Jeremiah 36:30 (ASV)

He shall have none to sit ... — The 3 months’ reign of Jehoiakim was too destitute of real power to be a contradiction to this prediction.
