Read near the end to show the Quran says it confirms what the Jews have and that they recite the scripture; used to reinforce that their book was present and authoritative.

Quran 2:40-44
quran
40 Children of Israel, remember My blessing wherewith I blessed you, and fulfil My covenant and I shall fulfil your covenant; and have awe of Me. 41 And believe in that I have sent down, confirming that which is with you, and be not the first to disbelieve in it. And sell not My signs for a little price; and fear you Me. 42 And do not confound the truth with vanity, and do not conceal the truth wittingly. 43 And perform the prayer, and pay the alms, and bow with those that bow. 44 Will you bid others to piety, and forget yourselves while you recite the Book? Do you not understand?
Quoted at the outset to argue that Surah 2 tells the Children of Israel to believe the Quran because it 'verifies what is with you,' while also assuming they still 'read the Book'; the speakers used it as a core proof that the Quran affirms the scriptures Jews possessed in Muhammad's time.
