(Ibid. 9) "And Yithro rejoiced over all the good": R. Yehoshua says: Scripture speaks of the good of the manna. They said to him: In this manna that the L–rd has given us we savor the taste of the loaf, of flesh, of fish, of hoppers, of all the delicacies in the world, it being written "good," "the good," "all the good," "over all the good."
