“The mitzvah to ‘love your neighbor’ means that we should love all people, no matter which nation they belong to or what language they speak. For all human beings are created in the Divine Image…. Our love of humanity should not exclude any nation or individual. For the human was not created for his own sake exclusively, rather, all people exist for the sake of one another.”
(Sefer HaBrit (1797), Section 2, Discourse 13).
