Behold, you will call a nation that you do not know,
and a nation that did not know you will run to you,
because of Yahweh your God
and for the Holy One of Israel;
for he has glorified you.” Bible see other translations

“a nation that you do not know.” The Messianic kingdom will cover the whole earth and the Messiah will rule the whole earth, and people of every different nationality will come to him and serve him.
