The Holy Qur'an differentiates between Jews and children of Israel. If you read verses regarding the Jews, they are generally concerned with their relationship with Islam and Muslims. As for the verses about children of Israel, you will see the children of Israel are not presented to be current time, but rather about very old religious matters, through stories, with the aim of taking the lesson. You will see what happened between the children of Israel and God, or between them and his messengers. For example, God orders them and they break, and he punishes them.
