'Branches' in the Bible

And if the first-fruit is holy, so is the mass: and if the root is holy, so are the branches.

But if some of the branches were broken off, and you, an olive-tree of the fields, were put in among them, and were given a part with them in the root by which the olive-tree is made fertile,

Do not be uplifted in pride over the branches: because it is not you who are the support of the root, but it is by the root that you are supported.

You will say, Branches were broken off so that I might be put in.

For, if God did not have mercy on the natural branches, he will not have mercy on you.

For if you were cut out of a field olive-tree, and against the natural use were united to a good olive-tree, how much more will these, the natural branches, be united again with the olive-tree which was theirs?
