Joel described the day of Yahweh. It would be a cloudy day of darkness and gloom. There would be a thick black darkness spread over the mountains. A great powerful army would come. They would be like no other army before or afterwards. This day of Yahweh bears a resemblance to the large swarm of locusts that created the impression of a dark day because of their huge numbers.
The Egyptians will slitter away like a snake as her enemies shall attack her in full force. They are coming with axes to kill her, as if they were clearing a forest. This enemy is like a large swarm of locusts that is so numerous that cannot be measured. Good daughter Egypt will be put to shame, as she will be handed over to the people from the north.
