Romans 11:16-18

16For if the firstfruit is holy, the lump is also holy : and if the root is holy, so are the branches.

17And if some of the branches were broken off, and thou, being a wild olive tree, wast grafted in among them, and with them partakest of the root and fatness of the olive tree;1

18Boast not against the branches. But if thou boastest, thou bearest not the root, but the root thee.
