ISA 49:6

6 And He said: It is too small a thing that Thou shouldest be Eved to Me to raise up the Shivtei Ya'akov, and to bring back the Netzurei Yisroel [(Preserved of Israel, the She'erit)]; I will also give Thee for Ohr Goyim, that Thou mayest be My Yeshu'ah [(Salvation)] unto the ketzeh ha'aretz.
