There was little Hope that the Jews Who lived during the Time of the Prophet could have believed

Allah said,

أَفَتَطْمَعُونَ

Allah reminds the Jews that He is omniscient, and knows what they try to keep concealed as well as what they say or do openly. So, it would make no difference at all, if the hypocrites tried to conceal their infidelity from the Muslims, or the other group, not to disclose the verses of the Torah which speak of the Holy Prophet ﷺ . For, Allah Himself has, on different occasions, informed the Muslims in the Holy Qur'an as to the hypocrisy of certain Jews and as to the testimony of the Torah also.

Verse 77 deals with the educated ones among the Jews, while Verse 78 speaks of those who were unlettered. These men had no knowledge of the Torah, and were even deficient in their understanding. Then, the Jewish scholars did not give them correct or proper information about their religion. No wonder, their minds were stuffed only with baseless superstitions which they found very pleasant and flattering.
