“King Joash was seven years old when he began to reign. He reigned forty years in Jerusalem. His mother’s name was Zibiah of Beer-sheba. King Joash did what was right in the sight of Yahweh all the days of the priest Jehoiada. Jehoiada got two wives for him. He had sons and daughters.”
This is almost word for word from 2 Kings, chapter 12, except there is nothing about how people were still worshipping and making sacrifices at the high places. This biblical chronicler decided not to mention that. King Joash was 7 when he was crowned king. King Joash ruled for 40 years so that his impact was important. He was a good king because he followed Yahweh as long as the priest Jehoiada was there to guide him. He had been instructed by the priest Jehoiada during his first 7 years. Once again we see the importance of early childhood learning. Zibiah was his mother but we never hear of her otherwise, unlike Athaliah or Jezebel. Notice the priest Jehoiada got him 2 wives.
