A Prophecy Against the Mountains of Israel (6:1–14)
8–10 But the Lord will spare some (verse 8); He will spare a remnant (Isaiah 10:20— 23). And that “remnant” would remember the Lord and repent and turn back to Him (verse 9). As always, the purpose of God’s DISCIPLINE and judgment is to lead people to repent; only those who refuse to repent bring final judgment down upon themselves.
11–14 Here the Lord further describes the coming judgment against Israel, against both the land and its people. The land will be laid waste from the desert to Diblah— that is, from one end to the other (verse 14).
