אִם־לֹ֣א תִשְׁמְע֡וּ וְאִם־לֹא֩ תָשִׂ֨ימוּ עַל־לֵ֜ב לָתֵ֧ת כָּב֣וֹד לִשְׁמִ֗י אָמַר֙ יְהוָ֣ה צְבָא֔וֹת וְשִׁלַּחְתִּ֤י בָכֶם֙ אֶת־הַמְּאֵרָ֔ה וְאָרוֹתִ֖י אֶת־בִּרְכֽוֹתֵיכֶ֑ם וְגַם֙ אָרוֹתִ֔יהָ כִּ֥י אֵינְכֶ֖ם שָׂמִ֥ים עַל־לֵֽב׃
萬軍的永恆者說：如果你們不聽從，如果你們不放在心上，不將榮耀歸給我的名，我就必使咒詛臨到你們，咒詛你們所得的福；其實我已經咒詛了它，因為你們不把這事放在心上。
Rashi
and I will curse And I will curse your blessings; how I should bless the grain, the wine, and the oil for you.
Rashi
Indeed I have [already] cursed it Indeed, it is unnecessary to have the matter depend on the condition upon which I made it depend: if they do not obey. For I know that you will not obey. Therefore, I have already cursed it - from now.
Tze'enah Ure'enah
“If you will not listen, and if you will not put it in your heart, etc.” [2:2]. If you priests will not listen to my words to give honor to My holy name, thus says the Holy One. I will send my curse on you and I will curse your blessings. That is to say, in place of blessing your grain, I will curse it. Though I have long cursed your grain, I will increase the curse greatly, because you have brought blind and lame sacrifices and will no longer listen to Me and take these words to heart.
