2 Kings 24:8

Jehoiachin was eighteen years old when he began to reign In 2 Chronicles 36:9, it is said that he was eight years old when he began to reign. But as both the Syriac and Arabic versions in that place read eighteen, it seems most reasonable to believe that the transcriber of the book of Chronicles made a mistake, and wrote eight for eighteen. Poole, however, and many other commentators, suppose that both places are correct, and that in his eighth year he began to reign with his father, who made him king with him, as divers other kings of Israel and Judah had acted in times of trouble; and that in his eighteenth year he reigned alone. Jehoiachin's succeeding his father in the throne of Judah may seem to disagree with the threat which the prophet denounces against his father, Jeremiah 36:30, He shall have none to sit upon the throne of David; but as Jehoiachin's reign lasted little more than three months, during which time he was absolutely subject to the Chaldeans, a reign of so short continuance, and of so small authority, may well be looked upon as nothing: see Ezekiel 19:6, &c.
