Gileadi restructures this verse to make a linked contrast between the first and second sentences:
"6 He said: It is too small a thing for you to be my servant to raise up the tribes of Jacob and to restore those preserved of Israel. I will also appoint you to be a light to the nations, that my salvation may be to the ends of the earth" (Gileadi, Avraham. The Book of Isaiah. Deseret Book Company, 1980, p. 193).
Gileadi's rendition provides a better conceptual linkage between the "light thing" of the restoration of Israel, and the additional mandate to be a light to the entire world. The servant has a wide ranging task which transends Israel, and encompasses all of the purposes of the Lord.
