Septuagint

And the deliverer shall come for Sionís sake, and shall turn away ungodliness from Jacob.  And this shall be my covenant with them, said the Lord
 

New Testament

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 with them, When I shall take away their sins 

Masoretic Text

And a Redeemer will come to Zion, and unto them that turn from transgression in Jacob, saith Jehovah.  And as for me, this is my covenant with them, saith Jehovah 

Comments:  The sense of the MT is somewhat different from the NT and the LXX.  In the MT, the Redeemer is pictured as coming to those in Jacob who repent.  In the NT and the LXX, the Redeemer cleanses Jacob of iniquity.
