תַּ֗חַת אֲשֶׁ֤ר לֹא־עָבַ֙דְתָּ֙ אֶת־יְהֹוָ֣ה אֱלֹהֶ֔יךָ בְּשִׂמְחָ֖ה וּבְט֣וּב לֵבָ֑ב מֵרֹ֖ב כֹּֽל

Because you would not serve your God יהוה in joy and gladness over the abundance of everything,

וְעָבַדְתָּ֣ אֶת־אֹיְבֶ֗יךָ אֲשֶׁ֨ר יְשַׁלְּחֶ֤נּוּ יְהֹוָה֙ בָּ֔ךְ בְּרָעָ֧ב וּבְצָמָ֛א וּבְעֵירֹ֖ם וּבְחֹ֣סֶר כֹּ֑ל וְנָתַ֞ן עֹ֤ל בַּרְזֶל֙ עַל־צַוָּארֶ֔ךָ עַ֥ד הִשְׁמִיד֖וֹ אֹתָֽךְ

you shall have to serve—in hunger and thirst, naked and lacking everything—the enemies whom יהוה will let loose against you. 

[God] will put an iron yoke upon your neck until you are wiped out. 

 

Deuteronomy 28:47-48
