Quran 5:20
And ˹remember˺ when Moses said to his people, “O my people! Remember Allah’s favours upon you when He raised prophets from among you, made you sovereign,1 and gave you what He had never given anyone in the world.
Quran 5:21. "O' my people! enter the holy land which Allah has ordained for you and do not turn your backs, for then you will return (Us) losers."
3. "Two men of those that feared (Allah) whom Allah had blessed, said: 'Enter against them by the gate! for when you have entered it, you will certainly be victorious. So, upon Allah should you rely if you are believers."
Kenge; There is difference between (were) and (are) Bani Israel were favorite people, not are favorite people. Qur'an mentions it in the past tense and invites Bani Israel. For example Jews to obey the last Messenger Muhammad, peace be upon him, but consumed by racial pride they insist on rejecting it because they insist that they are the chosen people and the final messenger has to be a Jew.
al-Maa’idah 5:64]
“Indeed, Allaah has heard the statement of those (Jews) who say: ‘Truly, Allaah is poor and we are rich!’ We shall record what they have said and their killing of the Prophets unjustly, and We shall say: ‘Taste you the torment of the burning (Fire).’”
[Aal ‘Imraan 3:181]
3.They distorted the word of Allaah, i.e., the Tawraat (Torah). Allaah says (interpretation of the meaning):
“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”
[al-Maa’idah 5:13]
“Then woe to those who write the Book with their own hands and then say, “This is from Allaah,” to purchase with it a little price! Woe to them for what their hands have written and woe to them for that they earn thereby”
[al-Baqarah 2:79]
4.They deserved the curse of Allaah, because of what Allaah has said about them. Allaah says:
“Those among the Children of Israel who disbelieved were cursed by the tongue of Dawood (David) and ‘Eesa (Jesus), son of Maryam (Mary). That was because they disobeyed (Allaah and the Messengers) and were ever transgressing beyond bounds.
They used not to forbid one another from Al-Munkar (wrong, evildoing, sins, polytheism, disbelief) which they committed. Vile indeed was what they used to do”
