A fire would destroy Nineveh, while the sword would chase people away. The city would be decimated, as if a swarm of locusts had come through there. They would have to multiply themselves like grasshoppers or locusts, as their merchants had done in the past. These commercial envoys of Nineveh were as numerous as the stars. Just as the locust sheds its skin, so that it can fly away, the guards at Nineveh would be like grasshoppers, hip hopping away. Their scribes were like swarms of locusts sitting on a fence on a cold day. However, when the sun came up the next day, these scribes would fly off, where no one would know where they went. As this was going to happen to Nineveh, no one would know where in the world they went.
Isaiah here assumes the first person plural “we,” instead of the first person singular, “I.” Now the tone is not as forgiving. They have heard of the pride, the arrogance, and insolence of Moab. Those Moabites make false boasts. Therefore, let them cry. Let everyone wail away, because they have been decimated. They cry out for their raisin cakes from Kir-hareseth. The raisin cakes were made from the grapes that dried up. These must have been some good bakery cakes from the town of Kir or Kerak in Moab, the probable names for Kir-hareseth.
