א וַיִּקְחוּ עַם־הָאָרֶץ אֶת־יְהוֹאָחָז בֶּן־יֹאשִׁיָּהוּ וַיַּמְלִיכֻהוּ תַחַת־אָבִיו בִּירוּשָׁלִָם

After the death of Yoshiyahu, the people of the land took Yeho’ahaz son of Yoshiyahu, who was not his firstborn son, and crowned him king in his father’s stead in Jerusalem.

ב בֶּן־שָׁלוֹשׁ וְעֶשְׂרִים שָׁנָה יוֹאָחָז בְּמָלְכוֹ וּשְׁלשָׁה חֳדָשִׁים מָלַךְ בִּירוּשָׁלִָם

Yo’ahaz was twenty-three years old when he became king, and he reigned for three months in Jerusalem. Three months passed until Pharaoh Nekho returned from his unsuccessful war in Karkemish and passed once again through the land of Judah, probably angry and bitter at his failure. Having killed Yoshiyahu, Pharaoh considered himself the supreme leader over Judah, and therefore refused to accept the appointment of Yeho’ahaz.
