A.T. Robertson Commentary Romans 11:19

"Thou wilt say then, Branches were broken off, that I might be grafted in." — Romans 11:19 (ASV)

Thou wilt say then (ερεις ουν). A presumptuous Gentile speaks.

That I might be grafted in (ινα εγω ενκεντρισθω). Purpose clause with ινα and first aorist passive subjunctive. He shows contempt for the cast-off Jews.
