כִּֽי־כֹה֙ אָמַ֣ר יְהוָ֔ה חִנָּ֖ם נִמְכַּרְתֶּ֑ם וְלֹ֥א בְכֶ֖סֶף תִּגָּאֵֽלוּ׃
װאָרום אַזױ האָט גאָט געזאָגט: אומזיסט זײַט איר פֿאַרקױפֿט געװאָרן, און ניט פֿאַר געלט װעט איר אױסגעלײזט װערן.
Rashi
You were sold for nought Because of worthless matters, i.e., the evil inclination, which affords you no reward.
Ibn Ezra
You have been sold, etc. I have sold you to the nations without receiving money for you, and so will I redeem you without giving money for you.
