'Broken off' in the Bible

But some of the branches [of a cultivated olive tree] were broken off [i.e., God's rejection of the Jews] and you [Gentiles], representing a wild olive tree [branch], were grafted into it. So then, you [Gentiles] were able to benefit from the roots and sap of the olive tree, along with the Jews.

But you [Gentiles] will then say, "The branches were broken off so that we could be grafted in."

True, but they [i.e., the Jews] were [really] broken off because they did not believe [in Christ], and you [Gentiles] remain [in God's favor] because you do believe [in Him]. So, do not become arrogant [about it], but be fearful.
