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׃
If ye will not hearken, and if ye will not lay it to heart, To give glory unto My name, Saith the LORD of hosts, Then will I send the curse upon you, And I will curse your blessings; Yea, I curse them, Because ye do not lay it to heart.
