Isaiah 49:5-6

And now the LORD says, who formed me in the womb to be his servant, to bring Jacob back to him, and that Israel might be gathered to him, for I am honored in the sight of the LORD, and my God has become my strength - he says, "It is too light a thing that you should be my servant to raise up the tribes of Jacob and to restore the survivors of Israel; I will give you as a light to the nations, that my salvation may reach to the end of the earth."

Luke 9:2-6

Jesus sent the twelve out to proclaim the kingdom of God and to heal. He said to them, "Take nothing for your journey, no staff, nor bag, nor bread, nor money-- not even an extra tunic. Whatever house you enter, stay there, and leave from there. Wherever they do not welcome you, as you are leaving that town shake the dust off your feet as a testimony against them." They departed and went through the villages, bringing the good news and curing diseases everywhere.
