'Off' in the Bible

I say then, Did God cast off his people? God forbid. For I also am an Israelite, of the seed of Abraham, of the tribe of Benjamin.

God did not cast off his people which he foreknew. Or know ye not what the scripture saith of Elijah? how he pleadeth with God against Israel:

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;

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:

The night is far spent, and the day is at hand: let us therefore cast off the works of darkness, and let us put on the armor of light.
