Romans 11:16-18

16Now if the firstfruits are holy, so is the whole batch. And if the root is holy, so are the branches.

17Now if some of the branches were broken off, and you, though a wild olive branch, were grafted in among them and have come to share in the rich root of the cultivated olive tree,

18do not boast that you are better than those branches. But if you do boast — you do not sustain the root, but the root sustains you.
