SALVATION Romans 11:11-12

Again I ask: Did they stumble so as to fall beyond recovery? Not at all! Rather, because of their transgression, salvation has come to the Gentiles to make Israel envious. But if their transgression means riches for the world, and their loss means riches for the Gentiles, how much greater riches will their full inclusion bring!

Again I ask: Did they stumble so as to fall beyond recovery? Not at all! 
Romans 11:1-2a  I ask then: Did God reject his people? By no means! I am an Israelite myself, a descendant of Abraham, from the tribe of Benjamin. God did not reject his people, whom he foreknew.

Rather, because of their transgression, salvation has come to the Gentiles 
Acts 13:46  Then Paul and Barnabas answered them boldly: "We had to speak the word of God to you first. Since you reject it and do not consider yourselves worthy of eternal life, we now turn to the Gentiles."

to make Israel envious 
Romans 11:13-14  I am talking to you Gentiles. Inasmuch as I am the apostle to the Gentiles, I take pride in my ministry in the hope that I may somehow arouse my own people to envy and save some of them.
Romans 10:19-21  Again I ask: Did Israel not understand? First, Moses says, "I will make you envious by those who are not a nation; I will make you angry by a nation that has no understanding." (Deuteronomy 32:21) And Isaiah boldly says, "I was found by those who did not seek me; I revealed myself to those who did not ask for me." (Isaiah 65:1) But concerning Israel he says, "All day long I have held out my hands to a disobedient and obstinate people." (Isaiah 65:2)

But if their transgression means riches for the Gentiles 
Romans 11:25-26a  I do not want you to be ignorant of this mystery, brothers and sisters, so that you may not be conceited: Israel has experienced a hardening in part until the full number of the Gentiles has come in, and in this way all Israel will be saved.
