Here the Muslims are addressed. In the early period of Islam - and especially after their exodus to Medina, where many Jews were then living - the Muslims expected that the Jews, with their monotheistic beliefs, would be the first to rally to the message of the Qur'an: a hope that was disappointed because the Jews regarded their own religion as a kind of national heritage reserved to the children of Israel alone, and did not believe in the necessity - or possibility - of a new revelation.
Cf. Jeremiah xxiii, 26- "Ye have perverted the words of the living God".
