John Gill Commentary Micah 6:13

"Therefore I also have smitten thee with a grievous wound; I have made thee desolate because of thy sins." — Micah 6:13 (ASV)

Therefore also will I make thee sick in smiting thee With the rod to be heard, (Micah 6:9) ; by sending among them some of his sore judgments, as famine, pestilence, the sword of the enemy, internal wars, and the like; which should cause their kingdom, and state, and families, to decline and waste away, as a sickly and diseased body.

So the Targum, "and I brought upon thee illness and a stroke." The Septuagint, Vulgate Latin, Syriac, and Arabic versions, render it, "and I began to smite thee"; as by Hazael, king of Syria, and Tiglathpileser, king of Assyria, who had carried part of them captive;

in making [thee] desolate because of thy sins ; went on, not only to make them sick, and bring them into a declining state, but into utter desolation; as by Shalmaneser, king of Assyria, who carried Israel captive; and by Nebuchadnezzar, king of Babylon, who led Judah captive, because of their sins of idolatry, injustice, and oppression, with others that abounded among them.
