What happened to the previous scriptures ?

(4 : 46)
Among those who are jews, there are some who displace words from
(their) right places and say: “We hear your word (O Muhammad (PBUH) )
and disobey,” and “Hear and let you (O Muhammad (PBUH) ) “hear
nothing.” And Raina with a twist of there tongues and as a mockery of
the religion (Islam) And if only they had said: “We hear and obey”,
And “Do make us understand,” it would have been better for them,
and more proper; but Allah has cursed them for their disbelief, so
they believe not except a few.


(5 : 13)
So because of their breach of their covenant, We cursed them and
made their hearts grow hard. They change the words from their
(right) places and have abandoned a good part of the Message that
was sent to them. And you will not cease to discover deceit in them,
except a few of them. But forgive them and overlook (their misdeeds).
Verily, Allah loves Al-Muhsinun (good-doers).
