Romans 11:16-18

If the first piece of bread is offered to God, then the whole loaf is made holy. If the roots of a tree are holy, then the tree’s branches are holy too. It is as if some of the branches from an olive tree have been broken off. You non-Jewish people are like the branch of a wild olive tree that has been joined to that first tree. You now share the strength and life of the first tree, the Jews. So do not brag about those branches that were broken off. If you brag, remember that you do not support the root, but the root supports you.
