From the kingdom, as the Targum; from having any share in the government, as she might have had during his minority, his mother being dead, as some conjecture; and not only took away her power and authority, but all the ensigns of it, and perhaps forbid her the court: or he removed her from the queen, his own wife, that she might not be corrupted by her; or rather it was from presiding over the rites of the idol next mentioned, and the worshipping of it:
because she had made an idol in a grove;
which had its name from horror and trembling; either because it was of a terrible aspect, or injected horror into its worshippers, or brought terrible calamities and judgments upon them: according to some Jewish writers F18, it was a Priapus, of an obscene figure; and so others F19, who suppose she presided over the sacred rites of this impure deity, the same with Baalpeor; and the Heathens used to place Priapus in their gardens F20, to fright away birds, (See Gill on Jeremiah 49:16), others take it to be Pan, from whence the word "Panic", used for any great fright:
and Asa destroyed her idol, and burnt it by the brook
and cast the ashes of it into it, that none might have any profit by it, the gold and silver on it, and in indignation to it, see ( Exodus 32:20 ) .
