Romans 11:24-25

For if you were cut off from your native wild olive tree and against nature were grafted into a cultivated olive tree, how much more will these — the natural branches — be grafted into their own olive tree? I don’t want you to be ignorant of this mystery, brothers and sisters, so that you will not be conceited: A partial hardening has come upon Israel until the fullness of the Gentiles has come in.
