Micah announces that Samaria will be made “a heap in the open country” and her stones poured into the valley. He connects this ruin to Israel’s rebellion and to the way idolatry and illicit gain shaped the city’s life (Micah 1:6–7).
In Micah 1:5–7 the speaker explains why disaster is coming: it is because of Israel’s rebellion, traced to its capitals and worship centers. These verses sit inside Micah’s opening announcement of coming upheaval (1:2–7), where the prophet portrays the divine ruler as entering the scene and the land reacting.
Micah 1:5–7 links the coming catastrophe directly to wrongdoing. The text is explicit: “all this” happens because of “the disobedience/transgression” and “sins” of Jacob/Israel (verse 5). The passage also concentrates responsibility in the capitals: Samaria represents Israel’s rebellion, and Jerusalem represents Judah’s “high places” (verse 5).
A careful answer keeps the immediate passage, the book's argument, and the whole-Bible storyline together, so the question is answered in context instead of as a detached idea.
Start with Micah 1:6-7, then read the surrounding section so the answer stays connected to the passage's flow.
6Therefore I will make Samaria as a heap of the field, [and] as places for planting vineyards; and I will pour down the stones of it into the valley, and I will uncover the foundations of it.
7All her engraved images shall be beaten to pieces, and all her hires shall be burned with fire, and all her idols will I lay desolate; for of the hire of a prostitute has she gathered them, and to the hire of a prostitute shall they return.
