כִּֽי־קֵרְב֧וּ כַתַּנּ֛וּר לִבָּ֖ם בְּאָרְבָּ֑ם כָּל־הַלַּ֙יְלָה֙ יָשֵׁ֣ן אֹֽפֵהֶ֔ם בֹּ֕קֶר ה֥וּא בֹעֵ֖ר כְּאֵ֥שׁ לֶהָבָֽה׃
Denn sie haben ihr Herz wie einen Ofen bereit gemacht, während sie auf der Lauer liegen; Ihr Bäcker schläft die ganze Nacht. Am Morgen brennt es wie ein flammendes Feuer.
Rashi on Hosea
For they have made ready their heart like an oven with their ambush They prepared and readied their heart with their ambush, like an oven which they prepare and heat in order to bake.
Rashi on Hosea
all night their baker sleeps Their baker, who heats the oven after they have prepared their heart and have thought of the execution of the evil, how they would do it.
Rashi on Hosea
their baker sleeps i.e., until morning they sleep, and in the morning they burn like fire until they consummate their evil.
