I have seen servants upon horses,.... Which being scarce in Judea, were only rode upon by princes and great personages, or such as were in affluent circumstances; and therefore it was an unusual and disagreeable sight to see servants upon them, which was a token of their being advanced upon the ruin and destruction of their masters; a reigning servant is not only uncomely, but one of the things by which the earth is disquieted, and it cannot bear, Pr 30:21; the Parthians and Persians distinguished their nobles and the vulgar, freemen and servants, by this; the servants went on foot, and the freemen rode on horses ;and princes walking as servants upon the earth; degraded from their honour; banished from their thrones and palaces, or obliged to leave them, and reduced to the lowest state and condition: so David, when his son rebelled against him, and he was forced to flee from him, and walk on foot, 2Sa 15:30; Alshech thinks it may be a prophecy of the captivity of Israel, when they walked as servants on the earth, and the Gentiles rode on horses.
