דברי הימים ב כ״ה:כ״ה-כ״ו:ב׳

ומעת אשר סר אמציה מאחרי ה'. ונפל לפני מלך ישראל מיד ויקשרו עליו קשר בירושלים להרגו כי הי' לבם דוה איש על בנו ועל אחיו ועל קרובו שנהרגו על ידו לפי שנתגרה במלך ישראל:

And from the time that Amaziah turned away from following the Lord and was defeated by the king of Israel, immediately they conspired against him in Jerusalem to kill him, because each one was grieved over his son, his brother, and his kinsman who were slain because of him, because he provoked the king of Israel.

וינס לכישה. עיר מבצר אשר נלחם עליה סנחריב ונס לכישה ויהי שם ט"ו שנים עד ששלחו אחריו לכיש' וימיתהו שם ואותן ט"ו שנה שהי' בלכיש מלכה יכליהו אם עזיהו תחתיו אך קשה לי ובפי' ר' יוסף זצ"ל ראיתי גם אותן ט"ו שנים שהי' בלכיש מלך עזיהו בנו תחתיו ולא נכון לפותרו כן שהרי כתיב בסמוך והוא בן שש עשר' שנה נמצא שלא היה בזמן שברח אביו אלא בן שנה ועוד שא"כ היה לו לומר ויקחו את עזיהו וימליכו תחת אביו בחייו אלא משמע שלא מלך בחיי אביו:

and he fled to Lachish a fortified city against which Sennacherib waged war. He fled to Lachish, where he remained fifteen years until they followed him to Lachish and assassinated him there. And during those fifteen years that he was in Lachish, Jecoliah, Uzziah’s mother, reigned in his stead. This is how it appears to me. In the commentary of Rabbi Joseph (Kara), I saw that during those fifteen years that he was in Lachish, Uzziah his son reigned in his stead, but it is incorrect to interpret it in this manner, for it is written immediately following (26:1): “who was sixteen years old.” We find that when his father fled, he was only one year old. Moreover, if this is the case, it should say, “took Uzziah and made him king instead of his father during his lifetime.” Rather, Scripture intimated that he did not reign during his father’s lifetime.
