Josiah son of Amon became king of Judah, reigning at age 8 for 31 years from Year 3285 [(until Year 3316, Seder Olam)]. Pharaoh Necho killed him, and in the 8th year of his reign, which was Year 3292, he began to seek God [(Divrei HaYamim II 35)], and in year 12, which was Year 3297, he began to purify Judah and Jerusalem [(Tzeda LaDerech)]. Chilkiah was Zephaniah's 22nd descendant, and Yirmiyahu [(Baruch, Shir HaShirim chapter 19 b)] and Chuldah were prophets.
And the king, on the advice of Yirmiyahu, hid the Ark, the anointing oil, the Tablets, the jar of manna, the staff, and many sacred ornaments in a cave beneath the Temple [(Shir HaShirim). Achaz reincarnated in Josiah and was killed in war to atone for the sins of the previous incarnation, and all of a quarter was considered death by itself, and this is the meaning of "HaShem is righteous for I have rebelled against His word" - the righteous judged himself (Sefer Sod Bereishit).
Josiah reincarnated in Rabbi Yishmael son of Elisha the High Priest (Asarah Harugei)]. Some say in his days Ahasuerus king of Persia destroyed Nineveh until its place was unknown, and in the Book of Nineveh it was swallowed up in the lower netherworld, and I thought that the Nineveh in the days of Rabbeinu HaKadosh in Tractate Ta'anit is not this Nineveh [(Shir HaShirim) see Year 3319]. And its land became dark and desolate, and after three days passed, he came to observe - when the river passed he came to new Nineveh, and there were seven thousand Speakers of the Targum language [(Benjamin of Tudela)].
