4:11 At that time shall it be said to this people and to Jerusalem, A dry {i} wind of the high places in the wilderness toward the daughter of my people, not {k} to fan, nor to cleanse,
(i) The north wind by which he means Nebuchadnezzar.
(k) But to carry away both corn and chaff.
4:11 At that time - There shall be tidings brought both to the country and city. A dry wind - A drying wind, such as shall blast and scorch where it comes, without any rain or moisture. It points at the stormy and furious irruption of the Babylonian army. In the plain - Where there is no stop in the way to break its fury. Toward - Directly, and designedly, coming in the way leading to my people. Not - Not such a gentle wind, as is made choice of to separate the chaff from the wheat; but so boisterous and violent, that it shall sweep away, and lay waste, all together.
4:5-18 The fierce conqueror of the neighbouring nations was to make Judah desolate. The prophet was afflicted to see the people lulled into security by false prophets. The approach of the enemy is described. Some attention was paid in Jerusalem to outward reformation; but it was necessary that their hearts should be washed, in the exercise of true repentance and faith, from the love and pollution of sin. When lesser calamities do not rouse sinners and reform nations, sentence will be given against them. The Lord's voice declares that misery is approaching, especially against wicked professors of the gospel; when it overtakes them, it will be plainly seen that the fruit of wickedness is bitter, and the end is fatal.
