Or HaChaim on Deuteronomy 32:13/אור החיים על דברים ל״ב:י״ג

1 ירכיבהו על במותי ארץ, He makes him ride on the heights of the earth." This verse is not the continuation of what has been written immediately before, but it is the beginning of a new subject and the verse belongs to what follows. The basic subject being introduced here is וישמן ישורון, "Yeshurun became fat and kicked."
