What does Micah 1:5 mean?

All this is happening because of how Jacob’s people have rebelled, because of the sins of Israel. What’s the source of Jacob’s rebellion? Isn’t it Samaria? And what’s Judah’s high place? Isn’t it Jerusalem? Micah 1:5 - Modern Text Bible

(The reason for this judgment is the people’s unfaithfulness. The capitals—Samaria and Jerusalem—are at the heart of the problem.)
