וְשָׁמַטְתָּ֗ה וּבְךָ֙ מִנַּחֲלָֽתְךָ֙ אֲשֶׁ֣ר נָתַ֣תִּי לָ֔ךְ וְהַעֲבַדְתִּ֙יךָ֙ אֶת־אֹ֣יְבֶ֔יךָ בָּאָ֖רֶץ אֲשֶׁ֣ר לֹֽא־יָדָ֑עְתָּ כִּֽי־אֵ֛שׁ קְדַחְתֶּ֥ם בְּאַפִּ֖י עַד־עוֹלָ֥ם תּוּקָֽד׃ (ס)
你必親身被迫撒手，離開我賜給你的產業；我必使你在你所不認識的地上服事你的仇敵；因為你們在我的怒中點起了火，這火必永遠燃燒。
Ibn Ezra
ignites “Jealousy”, or “that which they do” is the implied subject of this verb, which we find used only transitively (e.g., “for you have kindled fire in My nostrils” [Jeremiah 17: 4]). But it is also plausible that here the word means is ignited (as in “all these joined” [Genesis 14: 3] — meaning, were joined). In any case, the image denotes anger.
Rashbam
והעתרתי, a similar construction to vehacharamti in Numbers 21,2 והחרמתי את עריהם, “I will destroy their cities.” Another similar construction occurs in Ezekiel 26,3 והעליתי, and in Jeremiah 17,2 we find והעבדתיך, in all these examples the letters אהחע determine which vowels are used in this type of future tense, introduced by the inverted letter vav, if it is in the future tense or in the past tense. If it were in the ordinary past tense however, it should have read: he-evarti, he-eliticha, instead of ha-avarti and ha-aliticha. [the author quotes a few more examples which we can dispense with. Ed.]
