Jamieson, Fausset and Brown on Ezekiel 34:17

17. you, ... my flock--passing from the rulers to the people.

cattle and cattle--rather, "sheep and sheep"; Margin, "small cattle," or "flocks of lambs and kids," that is, I judge between one class of citizens and another, so as to award what is right to each. He then defines the class about to be punitively "judged," namely, "the rams and he-goats," or "great he-goats" (compare Is 14:9, Margin; Zec 10:3; Mt 25:32, 33). They answer to "the fat and strong," as opposed to the "sick" (Eze 34:16). The rich and ungodly of the people are meant, who imitated the bad rulers in oppressing their poorer brethren, as if it enhanced their own joys to trample on others' rights (Eze 34:18).
