'Grafted' in the Bible

Now if some of the branches have been broken out, and thou, being a wild olive tree, hast been grafted in amongst them, and hast become a fellow-partaker of the root and of the fatness of the olive tree,

Thou wilt say then, The branches have been broken out in order that I might be grafted in.

And they too, if they abide not in unbelief, shall be grafted in; for God is able again to graft them in.

For if thou hast been cut out of the olive tree wild by nature, and, contrary to nature, hast been grafted into the good olive tree, how much rather shall they, who are according to nature be grafted into their own olive tree?
