His mother was Jehoaddan (2 Kings 14:1–4) and his son was Uzziah (2 Chronicles 26:1). He took the throne at the age of 25, after the assassination of his father, and reigned for 29 years, (2 Kings 14:2, 2 Chronicles 25:1) 24 years of which were with the co-regency of his son. The second Book of Kings and the second Book of Chronicles in the Hebrew Bible consider him a righteous king, but with some hesitation.[2] He is praised for killing the assassins of his father only and sparing their children, as dictated by the law of Moses.
