וְהַבָּמ֖וֹת לֹא־סָ֑רוּ רַ֣ק לְבַב־אָסָ֗א הָיָ֥ה שָׁלֵ֛ם עִם־יְהוָ֖ה כָּל־יָמָֽיו׃
오직 산당은 없이하지 아니하니라 그러나 아사의 마음이 일평생 여호와 앞에 온전하였으며
Rashi on I Kings
[However] the [private] altars he did not remove. The private altars upon which they had become accustomed to sacrifice to Heaven since Shiloh had been destroyed until the Beis [Hamikdosh] was built, when private altars were permissible, were not removed now, even though they were forbidden once the Beis [Hamikdosh] was built, and they were punished by premature death because of it.
