Love all people. How so? This teaches us that a person should love all people and not hate anyone. For so we find with the people of the Generation of the Dispersion [at the time of the Tower of Babel], that because they loved one another, the Holy Blessed One did not want to wipe them off the face of the earth, but instead only scattered them to the four corners of the world. (Avot D'Rabbi Natan 12:7)
