Romans 11:16-21

If the first piece of dough is holy, the lump is also; and if the root is holy, the branches are too. But if some of the branches were broken off, and you, being a wild olive, were grafted in among them and became partaker with them of the rich root of the olive tree, do not be arrogant toward the branches; but if you are arrogant, remember that it is not you who supports the root, but the root supports you. You will say then, “Branches were broken off so that I might be grafted in.” Quite right, they were broken off for their unbelief, but you stand by your faith. Do not be conceited, but fear; for if God did not spare the natural branches, He will not spare you, either.
