Exodus 9:10

10 And they took ashes of a chimney, and they stood before Pharaoh; and Moses sprinkled it into heaven; and wounds of swelling bladders were made in men, and in work beasts; (And so they took some ashes from a chimney, and they stood before Pharaoh; and Moses tossed it into the air; and sores of swelling boils were made on the people, and on the work beasts;)

Exodus 9:10 Meaning and Commentary

Exodus 9:10

And they took ashes of the furnace
Which was near at hand, perhaps in Pharaoh's kitchen: and stood before Pharaoh;
not in his palace, or in any covered room, but in some place open to the heaven, a courtyard or garden adjoining to the palace: and Moses sprinkled it up towards heaven; cast it up in the air; this being again ascribed to Moses, seems to confirm the notion of those who think he only did it; but, for the reasons before given, both may be thought to be concerned: and it became a boil breaking forth with blains, upon man, and upon
beast;
these failing down in the manner before described, on whomsoever they lighted, whether man or beast, produced sore boils and inflammations, and raised blisters and blotches; and hence arose those lying scandalous stories of the Israelites being a scabby people, and of their being driven out of Egypt on that account, affirmed by Manetho, Lysimachus, Diodorus Siculus, Tacitus, Justin, and others; (See Gill on Exodus 4:6) with this plague the first vial poured forth on mystical Egypt, or antichrist, has some agreement, ( Revelation 16:2 ) .

Exodus 9:10 In-Context

8 And the Lord said to Moses and Aaron, Take ye your hands full of ashes of a chimney, and Moses sprinkle it into heaven before Pharaoh; (And the Lord said to Moses and Aaron, Take ye some handfuls of ashes from a chimney, and Moses toss it into the air before Pharaoh;)

9 and be there dust on all the land of Egypt; for why botches shall be in men, and in work beasts, and swelling bladders shall be in all the land of Egypt. (and let there be dust in all the land of Egypt; and let it bring forth sores of swelling boils on the people, and on the work beasts, in all the land of Egypt.)

10 And they took ashes of a chimney, and they stood before Pharaoh; and Moses sprinkled it into heaven; and wounds of swelling bladders were made in men, and in work beasts; (And so they took some ashes from a chimney, and they stood before Pharaoh; and Moses tossed it into the air; and sores of swelling boils were made on the people, and on the work beasts;)

11 and the witches might not stand before Moses, for the wounds, or sores, that were in them, and in all the land of Egypt. (and the witches could not stand up before Moses, because of the sores that were on them, and on all the Egyptians.)

12 And the Lord made hard the heart of Pharaoh, and he heard not them, as the Lord spake to Moses. (But the Lord hardened Pharaoh's heart, and he would not listen to them, as the Lord had said to Moses.)
