'Broken off' in the Bible

Now if some of the branches were broken off, and you, [although you] were a wild olive tree, were grafted in among them and became a sharer of the root of the olive tree's richness,

Then you will say, "Branches were broken off in order that I could be grafted in."

Well said! They were broken off because of unbelief, but you stand firm because of faith. Do not think arrogant [thoughts], but be afraid.
