Consider this mystery as we see it here below. When all the souls are able to attach themselves to the Shechinah (Divine Presence), each one then shows love to the other and Israel are called “one nation on earth” (Chronicles I, 17:21 etc.). For they literally become brothers and friends who are all running towards a single goal. However, when this is not the case but instead each is intent only on his own one-sided gain, there can be nothing but hatred. However, such a bond can exist only at a time of great repair, such as at the time of the Giving of the Torah at Sinai, of which it is written, “Israel encamped there facing the mountain” (Exodus 19:2; the singular form of “encamped” indicates their unity at that time, see Rashi ad loc.). And it will be the same in the future.
