Reading Amos Chapters 1-9 in my Bible reading plan.  Israel's destruction is coming because they did not serve God, depended on earthen 'stuff' for their faith and protection, and were led by wicked kings.

Empty worship in the Temple.  Crushed the poor, disowned the widows.  The land will be barren, day will become night, you will thirst for water.  They will be carried away to other lands.

V 10  All the sinners of my people shall die by the sword, which say, The evil shall not overtake nor prevent us.  11 In that day will I raise up the tabernacle of David that is fallen, and close up the breaches thereof;  and I will raise up his ruins, and I will build it as in the days of old.

V 15  And I will plant them upon their land, and they shall no more be pulled up out of their land which I have given them, saith the Lord thy God.

There was always a remant of faithful in Israel that worshiped and honored God's commands.  He never forsakes the truly faithful.
