Passage
And their king shall go into captivity, he and his princes together, saith Jehovah.
And their king shall go into captivity, he and his princes together, saith Jehovah.
Amos 1:13 Thus saith Jehovah: For three transgressions of the children of Ammon, and for four, I will not revoke its sentence; because they ripped up the women with child of Gilead, that they might enlarge their border.
Amos 1:14 And I will kindle a fire in the wall of Rabbah, and it shall devour the palaces thereof, with shouting in the day of battle, with a tempest in the day of the whirlwind.
Amos 1:15 And their king shall go into captivity, he and his princes together, saith Jehovah.
The verse centers on "king", "shall", "captivity", "princes", "together", "saith", and "jehovah". It is saying that the verse draws attention to "king" and "shall", so its meaning should be read from those terms before moving to application.
The prior verse says "And I will kindle a fire in...", giving immediate footing for "king" and "shall". In Amos context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "king" and "shall" with trust shaped by these words, not by a vague optimism outside the passage.
