1 Nephi 21:6

And he said:

It is a light thing

that thou shouldst be my servant

to raise up the tribes of Jacob,

and to restore the preserved of Israel.

I will also give thee for a light to the Gentiles,

that thou mayest be my salvation unto the ends of the earth.

that thou shouldst be my servant
