15. For if the casting away of them be the reconciling of the world, what shall the receiving of them be, but life from the dead?
16. For if the firstfruit be holy, the lump is also holy: and if the root be holy, so are the branches.
17. And if some of the branches be broken off, and thou, being a wild olive tree, wert grafted in among them, and with them partakest of the root and fatness of the olive tree;
18. Boast not against the branches. But if thou boast, thou bearest not the root, but the root thee.
19. Thou wilt say then, The branches were broken off, that I might be grafted in.
20. Well; because of unbelief they were broken off, and thou standest by faith. Be not highminded, but fear:
21. For if God spared not the natural branches, take heed lest he also spare not thee.
