بِئْسَمَا اشْتَرَوْا بِهِ أَنفُسَهُمْ أَن يَكْفُرُوا بِمَا أَنزَلَ اللَّهُ بَغْيًا أَن يُنَزِّلَ اللَّهُ مِن فَضْلِهِ عَلَىٰ مَن يَشَاءُ مِنْ عِبَادِهِ ۖ فَبَاءُوا بِغَضَبٍ عَلَىٰ غَضَبٍ ۚ وَلِلْكَافِرِينَ عَذَابٌ مُّهِينٌ

Wretched is the price for which they sold themselves — denying what God has sent down, resentful that God would bestow his grace upon whichever of his servants he wills. So they drew upon themselves wrath upon wrath. And for those who deny, there is a humiliating punishment.
Baghy, the word for what motivates the refusal, means overstepping out of resentment, and it is aimed here at the recipient rather than the message. Wrath is then described as arriving upon wrath, a doubling the Arabic states plainly and commentators read as one for each refusal. The grace being resented is described as given to whichever servants God wills, which is the sentence the resentment fastens on.
