For her wound is incurable; for it is come unto Judah; he is come unto the gate of my people, even to Jerusalem.

Wesley's Notes

1:9 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.

King James Translators' Notes

her...: or, she is grievously sick of her wounds

Jamieson-Fausset-Brown Bible Commentary

9. 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;37:33-37).

Matthew Henry's Concise Commentary

1:8-16 The prophet laments that Israel's case is desperate; but declare it not in Gath. Gratify not those that make merry with the sins or with the sorrows of God's Israel. Roll thyself in the dust, as mourners used to do; let every house in Jerusalem become a house of Aphrah, a house of dust. When God makes the house dust it becomes us to humble ourselves to the dust under his mighty hand. Many places should share this mourning. The names have meanings which pointed out the miseries coming upon them; thereby to awaken the people to a holy fear of Divine wrath. All refuges but Christ, must be refuges of lies to those who trust in them; other heirs will succeed to every inheritance but that of heaven; and all glory will be turned into shame, except that honour which cometh from God only. Sinners may now disregard their neighbours' sufferings, yet their turn to be punished will some come.
