15 For if the casting away of them is the reconciling of the world, what shall the receiving of them be, but life from the dead?
16 For if the firstfruit is holy, so shall the rest be; and if the root is holy, so shall be the branches.
17 And if some of the branches were broken off, and thou, being a wild olive tree, wert grafted in among them and hath been made participant of the root and of the fatness of the olive tree,
18 do not boast against the branches. But if thou boast, know that thou dost not bear the root, but the root thee.
19 Thou wilt say then, The branches were broken off that I might be grafted in.
20 Good; because of their unbelief they were broken off, but thou by faith art standing. Do not be highminded, but fear
21 that if God did not forgive the natural branches, neither shall he forgive thee.
