Romans 11:19KJV

17And if some of the branches be broken off, and thou, being a wild olive tree, wert graffed in among them, and with them partakest of the root and fatness of the olive tree;

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

19Thou wilt say then, The branches were broken off, that I might be graffed in.

20Well; because of unbelief they were broken off, and thou standest by faith. Be not highminded, but fear:

21For if God spared not the natural branches, lest he also spare not thee.
