Romans 11:16-18

And if the firstfruit is holy, so is the lump: and if the root is holy, so are the branches. But 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; glory not over the branches: but if thou gloriest, it is not thou that bearest the root, but the root thee.
