3:1 This second oracle begins like the first and third ones, with a summons to hear the prophet's message (cf. 1:2; 6:1). The initial "And I said"ties this oracle to the preceding one and provides continuity. Micah asked rhetorically if it was not proper for Israel's rulers to practice justice (fairness, equity). It was not only proper, but it was essential. Again, Jacob and Israel are synonyms for all 12 tribes (cf. 1:5; et al.).
3:2-3 Yet these rulers had stood justice on its head. They hated good and loved evil (cf. Prov. 8:13; Isa. 1:16-17; Amos 5:15). Tearing the flesh off the people, eating their flesh, and cooking their bones all represent abuse of their victims for their own selfish ends. The figure is of a hunter, and the implication is that the rulers regarded and treated the ordinary citizens as mere animals rather than as human beings. The rich stripped the poor of their money and property and oppressed them unmercifully (cf. Zeph. 3:3)
3:4 Because these rulers had turned deaf ears to the pleas of orphans and widows, they would eventually cry out to Yahweh in prayer asking Him for help. But He would not answer them (cf. Ps. 27:7-9; Prov. 21:13; Jer. 7:12-15). God hiding His face from them is an anthropomorphism picturing God disregarding them, turning His back on them. God hears all prayers because He is omniscient, but He chooses not to respond to some of them.
