וַיִּשְׁלַ֣ח אֵלָ֣יו מַלְאָכִ֣ים ׀ לֵאמֹר֩ ׀ מַה־לִּ֨י וָלָ֜ךְ מֶ֣לֶךְ יְהוּדָ֗ה לֹא־עָלֶ֨יךָ אַתָּ֤ה הַיּוֹם֙ כִּ֚י אֶל־בֵּ֣ית מִלְחַמְתִּ֔י וֵאלֹהִ֖ים אָמַ֣ר לְבַֽהֲלֵ֑נִי חֲדַל־לְךָ֛ מֵאֱלֹהִ֥ים אֲשֶׁר־עִמִּ֖י וְאַל־יַשְׁחִיתֶֽךָ׃
尼哥差遣使者去見約西亞，說：«猶大王啊，我與你有甚麼相干呢？我今日不是來攻擊你，而是要攻擊與我交戰的那家；上帝已吩咐我要急速前行。你不要干預與我同在的上帝，免得祂毀滅你。»
From David to Destruction
Yoshiyahu HaMelech, entirely unnecessarily, enters into battle with Paroh Necho. Paroh Necho, according to the account in Divrei HaYamim II 35:21, even communicates to Yoshiyahu HaMelech that he is merely using Eretz Yisrael as a route to fight the Babylonians at the Battle of Carchemish. According to Chazal (Ta’anit 22b), Yirmiyahu Hanavi warns Yoshiyahu HaMelech against intervening.
Rashi
I will cause the sun to set at midday—When there will be exceeding tranquility, a sudden downfall will come and our Rabbis said: This refers to the day of Josiah who died by the “peaceful sword” as our Rabbis said: There was no more peaceful sword than Pharaoh-Neco who said to Josiah, (II Chron. 35:21) “What do I have to do with you, O king of Judah; not upon you yourself today.” Not upon you do I come today, but to pass through your land “to the house against which I wage war etc.” [from Mo’ed Katan, Ta’anith 22a]
