Adam Clarke on Micah 1:2

Hear, all ye people - The very commencement of this prophecy supposes preceding exhortations and predictions.

Hearken, O earth - ארץ arets, here, should be translated land, the country of the Hebrews being only intended.

And let the Lord God be Witness - Let him who has sent me with this message be witness that I have delivered it faithfully; and be a witness against you, if you take not the warning.

The Lord from his holy temple - The place where he still remains as your King, and your Judge; and where you profess to pay your devotions. The temple was yet standing, for Jerusalem was not taken for many years after this; and these prophecies were delivered before the captivity of the ten tribes, as Micah appears to have been sent both to Israel and to Judah. See Mic 1:5-9, Mic 1:12, Mic 1:13.
