Prophethood cannot be earned through one's own efforts or one's own merit; it is a special grace which Allah bestows on whomsoever He likes. But the Jews were so envious and malicious that they denied the Holy Prophet ﷺ and the Holy Qur'an out of sheer spite. In doing so, they were questioning the will of Allah Himself. Thus, they earned divine wrath in two ways - firstly, for denying a true prophet; and secondly؛ for their envy and malice.
The Holy Qur'an says that the Jews will have to undergo a punishment which would involve not only pain, but also disgrace and abasement. The latter condition has been added to suggest that this kind of punishment is peculiar to the infidels, and is not meant for a true Muslim at all, for a Muslim, no matter how great his sins are, will be punished for the purpose of being purified, not for being disgraced.
The next verse reports what the Jews used to say with regard to the Holy Qur'an, which clearly shows their envy and malice as well as their infidelity (Kufr کفر).
Mujahid said,
(How bad is that for which they have sold their own selves), "The Jews sold the truth for falsehood and hid the truth about Muhammad ." As-Suddi said that the Ayah,
(How bad is that for which they have sold their own selves) means, "The Jews sold themselves." meaning, what is worse is what they chose for themselves by disbelieving in what Allah revealed to Muhammad instead of believing, aiding and supporting him. This behavior of theirs is the result of their injustice, envy and hatred,
(grudging that Allah should reveal of His grace unto whom He wills of His servants). " There is no envy worse than this. Therefore,
(So they have drawn on themselves wrath upon wrath). Ibn `Abbas commented on this Ayah, "Allah became angry with them because they ignored some of the Tawrah and disbelieved in the Prophet that He sent to them." I (Ibn Kathir) say that the meaning of,
(And they drew on themselves) is that they deserved and acquired multiplied anger. Also, Abu Al-`Aliyah said, "Allah became angry with them, because of their disbelief in the Injil and `Isa and He became angry with them again, because they disbelieved in Muhammad and the Qur'an." Similar was said by `Ikrimah and Qatadah. Allah said,
(And for the disbelievers, there is disgracing torment). Since their disbelief was a result of their transgression and envy, which was caused by arrogance, they were punished with disgrace and humiliation in this world and the Hereafter. Similarly, Allah said,
(Verily, those who scorn My worship (i.e. do not invoke Me, and do not believe in My Oneness) they will surely enter Hell in humiliation!") (40:60) meaning, "Disgraced, degraded and humiliated." Imam Ahmad narrated that `Amr bin Shu`ayb said that his father said that his grandfather said that the Prophet said,
(The arrogant people will be gathered on the Day of Resurrection in the size of ants, but in the shape of men. Everything shall be above them, because of the humiliation placed on them, until they enter a prison in Jahannam called `Bawlas' where the fire will surround them from above. They shall drink from the puss of the people of the Fire.)
