What does Exodus 9:8 mean?
This begins to describe the sixth plague (Exodus 9:9–12). Like the third plague (Exodus 8:16), this one is unannounced. However, it is done in Pharaoh's presence so there is no doubt about its cause. The word for what Moses throws into the air is piyach, used only in this passage in Scripture. These are either the fine ashes from a furnace or a collection of the sooty residue left in its chimney. The result will be an outbreak of skin inflammations, diseases, and other conditions (Exodus 9:9).As with other disasters, this one is filled with symbolism. Kilns were used to bake bricks: the main task of Israel as slaves in Egypt (Exodus 1:11–14; 5:14). God's control over the Nile and animal life proved His superiority to Egyptian deities such as Khnum, Hapi, and Heqet. Plagues on livestock countered trust in idols like Hathor and Apis (Exodus 9:1–7). Rampant disease would counter the supposed powers of Isis and Sekhmet, both associated with health or disease. Soot falling to create a plague suggests an affliction coming from the heavens above.
