For if you were cut out of that which is by nature a mere wild olive tree, and have been grafted, contrary to nature, into a fruitful olive tree, how much more shall these, the natural branches, be regrafted into their own olive tree?

Now if the first-fruits of the dough Abraham and the Patriarchs are holy, so also is the whole mass their descendants. And if the root of a tree Abraham is holy, so also are the branches his descendants.
