R. Tarfon and the elders were once sitting in the shade of the grove of Yavneh when this question was once asked before them: Why need it be written (Genesis 37:25) "and their camels laden with spices, balm, and myrrh"? (He answered:) To apprise us of the extent to which the merit of the righteous comes to their aid. For if this "loved one" (Joseph) had gone down with (the usual wares of) the Arabs, would he not have died of the stench of the camels and the itran (a kind of resin)? But the Holy One Blessed be He "arranged" for him (a transport of) sacks full of spices and all goodly fragrances so that he not perish of their stench. (At this,) they said to him: You have taught us, our master, that this transpired in the merit of Joseph. They asked him: Our master, what is the blessing for one who drinks water to slake his thirst? He answered: "Who creates manifold beings and (supplies) their wants. (We thank you for) all that You have created—Life of the worlds!" They: You have taught us, our master, the blessing for one who drinks water to slake his thirst. Our master, in what merit did Judah attain to kingdom? R. Tarfon: You say. They: In the merit of his saying (Genesis, Ibid. 26) "What profit is it if we kill our brother, etc." by which he saved him from death. R. Tarfon: It suffices that this saving atone for his counsel to sell Joseph and not return him to his father.
