'Branches' in the Bible

Now if the firstfruits of the dough are holy, so also is the whole mass; and if the root of a tree is holy, so also are the branches.

And if some of the branches have been pruned away, and you, although you were but a wild olive, have been grafted in among them and have become a sharer with others in the rich sap of the root of the olive tree,

beware of glorying over the natural branches. Or if you are so glorying, do not forget that it is not you who uphold the root: the root upholds you.

"Branches have been lopped off," you will say, "for the sake of my being grafted in."

Do not be puffed up with pride. Tremble rather--for if God did not spare the natural branches, neither will He spare you.

and if you were cut from that which by nature is a wild olive and contrary to nature were grafted into the good olive tree, how much more certainly will these natural branches be grafted on their own olive tree?
