'Off' in the Bible

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;

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:

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