עַל־רָאשֵׁ֨י הֶהָרִ֜ים יְזַבֵּ֗חוּ וְעַל־הַגְּבָעוֹת֙ יְקַטֵּ֔רוּ תַּ֣חַת אַלּ֧וֹן וְלִבְנֶ֛ה וְאֵלָ֖ה כִּ֣י ט֣וֹב צִלָּ֑הּ עַל־כֵּ֗ן תִּזְנֶ֙ינָה֙ בְּנ֣וֹתֵיכֶ֔ם וְכַלּוֹתֵיכֶ֖ם תְּנָאַֽפְנָה׃
Di puncak-puncak gunung mereka mempersembahkan korban sembelihan, dan di bukit-bukit mereka membakar ukupan, di bawah pohon ek, pohon populir putih, dan pohon tarbantin, karena naungannya teduh. Itulah sebabnya anak-anak perempuanmu berzina, dan menantu-menantu perempuanmu berbuat serong.
Radak
תחת האלון, beneath the oak. This category of tree also appears in Hoseah 4,13 and in Ezekiel 27,6. According to Onkelos the word is the same as אלוני ממרא with the vowel tzeyreh, i.e. it describes a certain valley or a grove of trees. In Bereshit Rabbah 81,5 Rabbi Shemuel bar Nachman understands the meaning of the word alon as derived from the Greek, where it means “double, additional,” The Torah hints that before the mourning for Deborah was over, news reached Yaakov that his mother Rivkah had died.
Rashi
that you desired to worship idols under them, similar to what is stated (Hosea 4:13): “Under the oak and the aspen, and the elm, for its shade is good.”
Rashi
מקל לבנה STICKS OF לבנה — a tree that is called לבנה — just as you say (Hosea 4:13) “Under oaks and poplars (ולבנה)” I think it is what is called in old French tremble; English trembling-poplar, which is white.
