And I will stretch over Jerusalem the line {d} of Samaria, and the plummet of the house of Ahab: and I will wipe Jerusalem as a man wipeth a dish, wiping it, and turning it upside down.

(d) As I have destroyed Samaria and the house of Ahab so will I destroy Judah.

Wesley's Notes

21:13 The line - She shall have the same measure, the same judgments which Samaria had. The line is often put for one's lot or portion, because mens portions or possessions used to be measured by lines. A dish - As men do with a dish that hath been used, first wholly empty it of all that is in it, then throughly cleanse and wipe it; and lastly, turn it upside down, that nothing may remain in it; so will I deal with Jerusalem, throughly empty and purge it from all its wicked inhabitants. Yet the comparison intimates, that this should be in order to the purifying, not the final destruction of Jerusalem. The dish shall not be broken in pieces, or wholly cast away, but only wiped.

King James Translators' Notes

wiping...: Heb. he wipeth and turneth it upon the face thereof

Jamieson-Fausset-Brown Bible Commentary

13. the line of Samaria, and the plummet of the house of Ahab-Captives doomed to destruction were sometimes grouped together and marked off by means of a measuring-line and plummet (2Sa 8:2; Isa 34:11; Am 7:7); so that the line of Samaria means the line drawn for the destruction of Samaria; the plummet of the house of Ahab, for exterminating his apostate family; and the import of the threatening declaration here is that Judah would be utterly destroyed, as Samaria and the dynasty of Ahab had been.

I will wipe Jerusalem, &c.-The same doom is denounced more strongly in a figure unmistakably significant.

Matthew Henry's Concise Commentary

21:10-18 Here is the doom of Judah and Jerusalem. The words used represent the city emptied and utterly desolate, yet not destroyed thereby, but cleansed, and to be kept for the future dwelling of the Jews: forsaken, yet not finally, and only as to outward privileges, for individual believers were preserved in that visitation. The Lord will cast off any professing people who dishonour him by their crimes, but never will desert his cause on earth. In the book of Chronicles we read of Manasseh's repentance, and acceptance with God; thus we may learn not to despair of the recovery of the greatest sinners. But let none dare to persist in sin, presuming that they may repent and reform when they please. There are a few instances of the conversion of notorious sinners, that none may despair; and but few, that none may presume.
