....

Behold! when they meet the men of Faith, they say: "We believe": But when they meet each other in private, they say: "Shall you tell them what Allah hath revealed to you, that they may engage you in argument about it before your Lord?"- Do ye not understand (their aim)?  2:76 A Baqrah

It refers to the Jews for sure, and probably also to the Christians, who wanted to hide or had already changed many parts the original Divine contents of their Scriptures.  There were many such folks who pretended before the Muslims that they believed in the Message (the Quran) sent through the Final Messenger.  But when they went apart to their own people, they would discuss and decide not to mention the original contents of their Divine Scriptures because they were already violating it so much.  These people also thought that if the Muslims (followers of Islam) become aware of the Jews and Christians changing their original Divine Scriptures, they (Muslims) would have a valid argument against those Jews and Christians before Allah Almighty on the Day of Judgement.  They forgot that Allah Almighty already knows their intentions and practices as He is aware of every act and intention whether concealed or open. 

If you continue reading from Verses 2:77 to 2:80, my explanation will become clearer.
