Matthew 25:33

καὶ στήσει, etc., the bare placing of the parties already judges, the good on the right, the evil on the left; sheep, emblems of the former; goats, of the latter. Why? No profit from goats, much from sheep; from their wool, milk, lambs, says Chrys., Hom. lxxix. Lust and evil odour secure for the goat its unenviable emblematic significance, say others: “id animal et libidinosum et olidum” (Grotius). Lange suggests stubbornness as the sinister quality. More important is the point made by Weiss that the very fact that a separation is necessary implies that all were one flock, i.e., that the judged in the view of Jesus are all professing Christians, disciples true or false.
