Romans 11:16-18

Amplified Bible

¹⁶ If the first portion [of dough offered as the first fruits] is holy, so is the whole batch; and if the root (Abraham, the patriarchs) is holy, so are the branches (the Israelites).^(A)

¹⁷ But if some of the branches were broken off, and you [Gentiles], being like a wild olive shoot, were grafted in among them to share with them the rich root of the olive tree, ¹⁸ do not boast over the [broken] branches and exalt yourself at their expense. If you do boast and feel superior, remember that it is not you who supports the root, but the root that supports you.
