כִּֽי־אִם־כֹּ֤ה תַעֲשׂוּ֙ לָהֶ֔ם מִזְבְּחֹתֵיהֶ֣ם תִּתֹּ֔צוּ וּמַצֵּבֹתָ֖ם תְּשַׁבֵּ֑רוּ וַאֲשֵֽׁירֵהֶם֙ תְּגַדֵּע֔וּן וּפְסִילֵיהֶ֖ם תִּשְׂרְפ֥וּן בָּאֵֽשׁ׃
오직 너희가 그들에게 행할 것은 이러하니 그들의 단을 헐며 주상을 깨뜨리며 아세라 목상을 찍으며 조각한 우상들을 불사를 것이니라
Ibn Ezra
But thus i.e., Only this shall you do to them — because you are holy people — and you shall not make yourself loathsome through the objects of the Gentiles, who adorn themselves with monuments and with Ashera trees.
Rashbam
כי אם כה תעשו להם, “rather, this is what you shall do to them, etc.” תגדעון, the root גדע is used whenever something long is being cut down or felled; compare Psalms 75,11 וכל קרני רשעים אגדע, “and I will cut down all the horns of the wicked.”
