In a number of places throughout Shir Hashirim in addition to this verse, the “maidens” or “daughters” of Yerushalayim represent the nations of the world (see 1:5, 2:7, 3:5, 5:8, 8:4). The medieval commentator Rashi explains that this is because in the future, Yerushalayim will be the metropolis of all countries, and all people will accept its centrality. Though the nations of the world will one day accept Yerushalayim as their political and religious capital, the Jewish people have always seen it as their eternal capital, providing inspiration and the means for fulfilling their spiritual needs even when they were in exile.
