Romans 11:17-27 ASV
But if some of the branches were broken off, and thou, being a wild olive, wast grafted in among them, and didst become partaker with them of the root of the fatness of the olive tree; glory not over the branches: but if thou gloriest, it is not thou that bearest the root, but the root thee. Thou wilt say then, Branches were broken off, that I might be grafted in. Well; by their unbelief they were broken off, and thou standest by thy faith. Be not highminded, but fear: for if God spared not the natural branches, neither will he spare thee. Behold then the goodness and severity of God: toward them that fell, severity; but toward thee, God’s goodness, if thou continue in his goodness: otherwise thou also shalt be cut off. And they also, if they continue not in their unbelief, shall be grafted in: for God is able to graft them in again. For if thou wast cut out of that which is by nature a wild olive tree, and wast grafted contrary to nature into a good olive tree; how much more shall these, which are the natural branches, be grafted into their own olive tree?
For I would not, brethren, have you ignorant of this mystery, lest ye be wise in your own conceits, that a hardening in part hath befallen Israel, until the fulness of the Gentiles be come in; and so all Israel shall be saved: even as it is written,
There shall come out of Zion the Deliverer;
He shall turn away ungodliness from Jacob:
And this is my covenant unto them,
When I shall take away their sins.
