Therefore as I live, saith the LORD of hosts, the God of Israel, Surely Moab shall be as Sodom, and the children of Ammon as Gomorrah, even the breeding of nettles, and saltpits, and a perpetual desolation: the residue of my people shall spoil them, and the remnant of my people shall possess them.
Moab shall be as Sodom, and the children of Ammon as Gomorrah, even the breeding of nettles - or, the overspreading of nettles - i:e., a place overrun with them.
And salt pits - found at the south of the Dead Sea. The water overflows in spring, and salt is left by the evaporation. Salt land is barren (whence arose the usage of "sowing with salt" a destroyed city and depopulated region, Judges 9:45; margin, saltness for "barrenness," Psalms 107:34).
The remnant of my people shall possess them - i:e., their land; in retribution for their having occupied Judah's land.
