'Grafted' in the Bible

Now if some of the branches have been broken off, and you, a wild olive branch, have been grafted in their place to share the rich root of the olive tree,

Then you will say, "Branches were cut off so that I could be grafted in."

If the Jews do not persist in their unbelief, they will be grafted in again, because God is able to graft them in.

After all, if you were cut off from what is naturally a wild olive tree, and contrary to nature were grafted into a cultivated olive tree, how much easier it will be for these natural branches to be grafted back into their own olive tree!
