R. Eliezer says: Scripture speaks of the good of Eretz Yisrael. They said to him: The L–rd is destined to give us six good "measures": Eretz Yisrael, the world to come, the kingdom of the House of David, the new world, the (institution of) the Kehunah and that of the Leviyah, it being written "good," "the good," "all the good," "over (adding three to the first three) all the good."
