'Away' in the Bible

knowing this, that our old man was crucified with him , that the body of sin might be done away, that so we should no longer be in bondage to sin;

For if the casting away of them is the reconciling of the world, what'shall the receiving of them be , but life from the dead?

and so all Israel shall be saved: even as it is written, There shall come out of Zion the Deliverer; He shall turn away ungodliness from Jacob:

And this is my covenant unto them, When I shall take away their sins.

Now I beseech you, brethren, mark them that are causing the divisions and occasions of stumbling, contrary to the doctrine which ye learned: and turn away from them.
