2 Kings 12:1-2

Amplified Bible, Classic Edition

12 In the seventh year of Jehu, ^[a]Joash began to reign, and he reigned forty years in Jerusalem. His mother was Zibiah of Beersheba.

²Joash did right in the sight of the Lord all his days in which Jehoiada the priest instructed him.

2 Kings 12:1 Judah and Israel each had a king named Joash or Jehoash, and the Hebrew uses the two forms of the name interchangeably. Since the time of their reigns overlapped, it became difficult not to confuse them. So this version will call the first one Joash, referring to the king of Judah who began his reign at seven years of age, and the other one Jehoash (as the Hebrew does in II Kings 13:10 and 14:17), referring to the king of Israel who began his reign thirty-seven years later.
