76- WHEN THEY MEET THOSE WHO BELIEVE, THEY SAY: ‘WE BELIEVE’, BUT WHEN THEY MEET IN PRIVATE THEY SAY (TO EACH OTHER): ‘DO YOU TELL THEM WHAT ALLAH REVEALED TO YOU  SO THAT THEY MAY USE IT TO ARGUE AGAINST YOU BEFORE YOUR LORD, DO YOU HAVE NO UNDERSTANDING.

77- DO THEY NOT KNOW THAT ALLAH KNOWS WHAT THEY HIDE AND WHAT THEY REVEAL?

These Ayahs show the hypocrisy of the Jews themselves and their own lack of faith. 

As mentioned earlier, the Jews had knowledge from the Torah about the imminent arrival of a prophet, the last prophet.  They spoke about him to the Arabs of Medina.  However they would not believe in him because they hoped that the prophet would be of the descendants of Isaac not Ismail. This was not really true, for they also rejected Jesus, peace upon him.    

They did not wish the Muslims to know what is mentioned earlier in the Torah about the coming of Mohamed, prayer and peace upon him

They thought of deceiving the Muslims, and they thought of deceiving Allah .the Highest, and this was worse. 

-         They thought to deceive the Muslims by pretending to be Muslims themselves.

-         However thinking of deceiving Allah the Highest shows real weakness of their own faith or lack of it.

How?

They thought that if they continued to hide, what Allah revealed to them in the Torah about the coming of a prophet, then the Arabs will not have this knowledge to use against them on the Day of Judgment.  As if Allah the Highest does not know, and does not know what is inside them.  This definitely shows lack of Faith.  Allah the Highest said in the Quran: “TO ALLAH BELONGS ALL THERE IS IN THE HEAVENS AND IN THE EARTH AND WHETHER YOU REVEAL WHAT IS INSIDE YOU OR CONCEAL IT, ALLAH WILL HOLD YOU TO ACCOUNT FOR IT, THEN FORGIVES WHOM HE WILLS AND PUNISHES WHOM HE WILLS, FOR ALLAH HAS POWER OVER EVERY THING”.  (S:2 A:284)
