The review of the parallel history in the 2nd book of the Chronicles, will form the best comment on the history of Azariah. Though it be said he did that which was right in the sight of the Lord, it is intended by the expression only to imply that he did not abjure the worship of the Lord God of Israel and set up idols. It should seem that his name was more generally known by that of Uzziah, as he is uniformly called in the Chronicles; and the leprosy with which he was smitten is there more particularly recorded. See 2 Chronicles 26:1, throughout.
2 Kings 15:1-7
1 In the twenty and seventh year of Jeroboam king of Israel began Azariaha son of Amaziah king of Judah to reign.
2 Sixteen years old was he when he began to reign, and he reigned two and fifty years in Jerusalem. And his mother's name was Jecholiah of Jerusalem.
3 And he did that which was right in the sight of the LORD, according to all that his father Amaziah had done;
4 Save that the high places were not removed: the people sacrificed and burnt incense still on the high places.
5 And the LORD smote the king, so that he was a leper unto the day of his death, and dwelt in a several house. And Jotham the king's son was over the house, judging the people of the land.
6 And the rest of the acts of Azariah, and all that he did, are they not written in the book of the chronicles of the kings of Judah?
7 So Azariah slept with his fathers; and they buried him with his fathers in the city of David: and Jotham his son reigned in his stead.
