15For if the casting away of them [is] the reconciling of the world, what [shall] the receiving [of them be], but life from the dead?
16And if the firstfruit is holy, so is the lump: and if the root is holy, so are the branches.
17But if some of the branches were broken off, and thou, being a wild olive, wast grafted in among them, and didst become partaker with them of the root of the fatness of the olive tree;
18glory not over the branches: but if thou gloriest, it is not thou that bearest the root, but the root thee.
19Thou wilt say then, Branches were broken off, that I might be grafted in.
20Well; by their unbelief they were broken off, and thou standest by thy faith. Be not highminded, but fear:
21for if God spared not the natural branches, neither will he spare thee.
