'Off' in the Bible

I ask then, Has God cast off His People? No, indeed. Why, I myself am an Israelite, of the posterity of Abraham and of the tribe of Benjamin.

God has not cast off His People whom He knew beforehand. Or are you ignorant of what Scripture says in speaking of Elijah--how he pleaded with God against Israel, saying,

"Branches have been lopped off," you will say, "for the sake of my being grafted in."

This is true; yet it was their unbelief that cut them off, and you only stand through your faith.
