Ba'al Shem Tov
In the name of the Ba’al Shem Tov, this is the explanation: “There is reward that the ‘donkey’ [hamor] causes,” meaning by way of food and drink, which are physical [homer] matters, he causes this reward – by way of his elevating to the Cause of Elevation the holy spark that was crouching down between the stables, which was among the lower elements. (Or HaGanuz le-Tzadikim, Vayehi)
