Galatians 2:16

Yet we have da'as that a man cannot be YITZDAK IM HASHEM (be justified with G-d) by [depending on] the ma'asim of Gezetz (Law), but through emunah in Rebbe, Melech HaMoshiach Yehoshua. And we have come to have bitachon in Rebbe, Melech HaMoshiach Yehoshua, that we can be YITZDAK IM HASHEM (be justified with G-d) by emunah in Moshiach and not by ma'asim, because by taryag mitzvot KOL CHAI LO YITZDAK (all living shall not be justified).
