וְגַ֣ם ׀ אֶת־מַעֲכָ֣ה אִמּ֗וֹ וַיְסִרֶ֙הָ֙ מִגְּבִירָ֔ה אֲשֶׁר־עָשְׂתָ֥ה מִפְלֶ֖צֶת לָאֲשֵׁרָ֑ה וַיִּכְרֹ֤ת אָסָא֙ אֶת־מִפְלַצְתָּ֔הּ וַיִּשְׂרֹ֖ף בְּנַ֥חַל קִדְרֽוֹן׃
他又廢去他母親瑪迦太后的位分，因為她為亞舍拉造了可憎的偶像；亞撒砍下她的偶像，在汲淪溪邊焚燒了。
Rashi
For she had made a fearful image. Our Rabbis stated [that מפלצת is a combination of] מפליא ליצונתא [=extreme lasciviousness]. She made for it a phallic symbol,1Alternatively, an image that casts fear and dread unto its worshipers.—Radak and she would copulate with it every day.2Maseches Avodah Zarah 44a.
