Romans 11:18-23 KJV
boast not against the branches. But if thou boast, thou bearest not the root, but the root thee.
Thou wilt say then, The branches were broken off, that I might be graffed in.
Well; because of unbelief they were broken off, and thou standest by faith. Be not highminded, but fear: for if God spared not the natural branches, take heed lest he also spare not thee. Behold therefore the goodness and severity of God: on them which fell, severity; but toward thee, goodness, if thou continue in his goodness: otherwise thou also shalt be cut off. And they also, if they abide not still in unbelief, shall be graffed in: for God is able to graff them in again.
