Romans 11:11-12

11So I say, have they stumbled so as to fall [to spiritual ruin]? Certainly not! But by their transgression [their rejection of the Messiah] salvation has come to the Gentiles, to make Israel jealous [when they realize what they have forfeited].

12Now if Israel’s transgression means riches for the world [at large] and their failure means riches for the Gentiles, how much more will their fulfillment and reinstatement be!
