RA KOOK ON VaYishlach Part 2: I Have an Ox and a Donkey

Upon his return to Eretz Yisrael, Jacob sent a message to his brother Esau: “I have an ox and a donkey” (Gen. 31:6). Why was it necessary to tell Esau about this ox and donkey? According to the Midrash (Breishit Rabbah 75), Jacob was not speaking about the material possessions he had amassed, but about something of far greater significance. The ox refers to Mashiach ben Joseph, the precursive Messianic leader descended from Joseph. The ox is a symbol of the tribe of Joseph; both Jacob and Moses used the imagery of an ox when blessing Joseph (Gen. 49:6; Deut. 33:17). And the donkey? That is a reference to Mashiach ben David, the ultimate Messianic king descended from David, who will arrive as “a pauper riding on a donkey” (Zechariah 9:9). Why do we need two Messianic leaders? And why are they represented specifically by these two animals?
