Romans 11:23-25

New Century Version

²³ And if the Jews will believe in God again, he will accept them back. God is able to put them back where they were. ²⁴ It is not natural for a wild branch to be part of a good tree. And you who are not Jews are like a branch cut from a wild olive tree and joined to a good olive tree. But since those Jews are like a branch that grew from the good tree, surely they can be joined to their own tree again.

²⁵ I want you to understand this secret, brothers and sisters, so you will understand that you do not know everything: Part of Israel has been made stubborn, but that will change when many who are not Jews have come to God.
