2 Kings 14:23

In the fifteenth year of Amaziah the son of Joash king of Judah Jeroboam the son of Joash king of Israel began to reign in Samaria, and reigned forty and one years.

Jeroboam the son of Joash king of Israel. He had been previously associated with his father for several years in the government.

And reigned forty and one years. Ewald, Thenius, and others, maintain that an error in the Hebrew numeral letters has occurred here-the duration of Jeroboam's reign having been originally stated at 52 or 53 instead of 41 years. But such a supposition is exceedingly improbable, as it implies the mistake to be considered as not limited to one, but to have extended to several letters (see the notes at 2 Kings 15:8).
