Matthew Poole and continuators on 1 Kings 15:1

NOw in the eighteenth year of king Jeroboam the son of Nebat, reigned Abijam over Judah.

Obj. How can this be, when he Reigned 3 Years, ver. 2. and Asa, his Successor, began his Reign in the twentieth Year of Ieroboam, v. 9? Ans. Parts of Years are commonly called and accounted Years both in the old and New Testament, and in prophane Writers. So his Reign began with Ieroboam's 18th Year, and continued his whole 19th Year, and ended within his 20th Year, in which also Asa's Reign began. And thus one and the same Year may well be, as it frequently is, attributed to two several Persons.
