פירוש על דברי הימים ב 10:18

Hadoram He is identical with Adoniram (I Kings 4:6), for during Solomon’s time, he enjoyed great eminence, but in Rehoboam’s time his greatness was humbled. Therefore, he was called Hadoram.

and the Children of Israel pelted him with stones and because Rehoboam did not know the cause of the rebellion in which they turned away from him, he was slain when he requested the levy that Solomon had levied upon them.
