Divrey Hayamim Bais 27:6-8

Orthodox Jewish Bible

⁶ So Yotam became mighty, because he made the darkhei Yotam steadfast before Hashem Elohav.

⁷ Now the rest of the divrei Yotam, and all his milchamot, and his ways, lo, they are written in the sefer of the melachim of Yisroel and Yehudah.

⁸ He was five and twenty shanah when he began to reign, and reigned sixteen shanah in Yerushalayim.
