דברי הימים ב, פרק כ״א, פסוק ה׳

Jehoram assumed the throne at the age of thirty-two, and his time as king in Jerusalem lasted for a total of eight years [ביאור שטיינזלץ]. The details of his rule, along with the events that unfold in the subsequent period, are drawn directly from the parallel historical accounts recorded in the Book of Kings [מלבי״ם].
