Micah 1:9

“For her wound [is] incurable, etc.] Or her “stroke [is] desperate”f54. The ruin of Samaria, and the ten tribes, was inevitable; the decree being gone forth, and they hardened in their sins, and continuing in their impenitence; and their destruction was irrevocable; they were not to be restored again, nor are they to this day; nor will be till the time comes that all Israel shall be saved: or “she is grievously sick of her wounds”; just ready to die, upon the brink of ruin, and no hope of saving her; this is the cause and reason of the above lamentation of the prophet: and what increased his grief and sorrow the more was, for it is come unto Judah; the calamity has reached the land of Judah;…”

“wound . . . incurable--Her case, politically and morally, is desperate (Jer 8:22). it is come--the wound, or impending calamity (compare Isa 10:28). he is come . . . even to Jerusalem--The evil is no longer limited to Israel. The prophet foresees Sennacherib coming even "to the gate" of the principal city. The use of "it" and "he" is appropriately distinct. "It," the calamity, "came unto" Judah, many of the inhabitants of which suffered, but did not reach the citizens of Jerusalem, "the gate" of which the foe ("he") "came unto," but did not enter (Isa 36:1; Isa 37:33-37).”

“For her - Samaria’s Wound - o, (literally, her wounds, or strokes, (the word is used especially of those inflicted by God, (Leviticus 26:21; Numbers 11:33; Deuteronomy 28:59, Deuteronomy 28:61, etc.) each, one by one,) is incurable The idiom is used of inflictions on the body politic (Nahum 3:0 ult.; Jeremiah 30:12, Jeremiah 30:15) or the mind , for which there is no remedy. The wounds were very sick, or incurable, not in themselves or on God’s part, but on Israel’s. The day of grace passes away at last, when man has so steeled himself against grace, as to be morally dead, having deadened himself to all capacity of repentance. For it is come unto - (quite up to) Judah; he, (the enemy,) is…”

“Her wound - The wounds of Samaria, her own sins, and God's just displeasure. It is come - The contagion of her sins, and the indignation of God against it, have reached to Judah also, yea, to Jerusalem. Micah 1:10”

“1:9 into Judah . . . Jerusalem: The corruption now permeated the entire nation, north to south.”

“her wound is incurable: or, she is grievously sick of her wounds, Isa 1:5, Isa 1:6; Jer 15:18, Jer 30:11-15 it: Kg2 18:9-13; Isa 8:7, Isa 8:8 he: Mic 1:12; 2Chr. 32:1-23; Isa 10:28-32, Isa 37:22-36 Micah 1:10”
