1 sn The announcement of the fourth plague parallels that of the first plague. Now there will be flies, likely dogflies. Egypt has always suffered from flies, more so in the summer than in the winter. But the flies the plague describes involve something greater than any normal season for flies. The main point that can be stressed in this plague comes by tracing the development of the plagues in their sequence. Now, with the flies, it becomes clear that God can inflict suffering on some people and preserve others – a preview of the coming judgment that will punish Egypt but set Israel free. God is fully able to keep the dog-fly in the land of the Egyptians and save his people from these judgments.
