Romans 11:22 (KJV)

And if some of the branches be broken off, and thou, being a wild olive tree, wert graffed in among them, and with them partakest of the root and fatness of the olive tree;

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.

And they also, if they abide not still in unbelief, shall be graffed in: for God is able to graff them in again.

For if thou wert cut out of the olive tree which is wild by nature, and wert graffed contrary to nature into a good olive tree: how much more shall these, which be the natural branches, be graffed into their own olive tree?

For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in.

And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob:

For this is my covenant unto them, when I shall take away their sins.
