Divrey Hayamim Bais 34:1-3

Orthodox Jewish Bible

34 Yoshiyahu was 8 years old when he began to reign, and he reigned in Yerushalayim 31 shanah.

² And he did that which was yashar in the eyes of Hashem, and walked in the ways of Dovid Aviv, and veered off neither right nor left.

³ For in the eighth year of his reign, while he was yet na’ar (young), he began to seek after Elohei Dovid Aviv; and in the twelfth year he began to make tahor Yehudah and Yerushalayim from the high places, and the Asherim, and the pesilim, and the massekhot (molten images).
