5:7 In that day the remnant of Jacob will live all over the world scattered among the other nations. "The remnant of Jacob"is one of Micah's favorite terms for the believing Jews living in the "last days"(cf. 2:12; 4:7; 5:8; 7:18), and here it refers to them after God judges the nations (vv. 5b-6). The presence of the Jews will be a divine gift to the other people of the world, as dew and rain are to the earth (cf. Gen. 12:3). God will have sent them among the nations as He sends the dew and rain; their presence there will be due to His working, not the result of human choices or national policies ultimately.
5:8-9 The Israelites will be dominant and powerful over the other people of the world then but in an irresistible rather than a ferocious sense (v. 7; cf. Deut. 28:13). They will have the upper hand, and their enemies would not be able to rise up against them. What a change this will be compared to the downtrodden and abused condition that the Jews have known since Nebuchadnezzar!
