Exodus 9:8

“And the Lord said unto Moses and unto Aaron, etc.] This very probably was the day following, on the third day of the month Abib, about the eighteenth of March, that orders were given to bring on the following plague: take to you handfuls of ashes of the furnace; either in which the bricks were burnt, or rather in which food was boiled, since it can scarcely he thought there should be brickkiln furnaces so near Pharaoh’s court; though perhaps some reference may be had to them, and to the labour of the children Israel at them, and as a just retaliation for their oppression of them in that way. These ashes were such as were blown off the coals, and though fresh, yet not so hot but that they…”

“PLAGUE OF BOILS. (Exo 9:8-17) Take to you handfuls of ashes, &c.--The next plague assailed the persons of the Egyptians, and it appeared in the form of ulcerous eruptions upon the skin and flesh (Lev 13:20; Kg2 20:7; Job 2:7). That this epidemic did not arise from natural causes was evident from its taking effect from the particular action of Moses done in the sight of Pharaoh. The attitude he assumed was similar to that of Eastern magicians, who, "when they pronounce an imprecation on an individual, a village, or a country, take the ashes of cows' dung (that is, from a common fire) and throw them in the air, saying to the objects of their displeasure, such a sickness or such a curse shall…”

“This marks a distinct advance and change in the character of the visitations. Hitherto, the Egyptians had not been attacked directly in their persons. It is the second plague which was not preceded by a demand and warning, probably on account of the special hardness shown by Pharaoh in reference to the murrain. Ashes of the furnace - The act was evidently symbolic: the ashes were to be sprinkled toward heaven, challenging, so to speak, the Egyptian deities. There may possibly be a reference to an Egyptian custom of scattering to the winds ashes of victims offered to Typhon. return to 'Top of Page'”

“9:8-12 The sixth plague brought festering boils on humans and animals. At this point the magicians, far from being able to duplicate the sign, were unable to spare themselves from it. Their defeat was complete.”

“Take to: This was a significant command; not only referring to the fiery furnace, which was a type of the slavery of the Israelites, but to a cruel rite common among the Egyptians. They had several cities styled Typhonian, in which at particular seasons they sacrificed men, who were burnt alive; and the ashes of the victim were scattered upwards in the air, with the view, probably, that where any atom of dust was carried, a blessing was entailed. The like, therefore, was done by Moses, though with a different intention, and more certain effect. See Bryant, pp. 93-106. Exo 8:16 Exodus 9:9”

“The sixth plague smote man and beast with Boils Breaking Forth in Blisters. - שׁחין (a common disease in Egypt, Deu 28:27) from the unusual word שׁחן (incaluit) signifies inflammation, then an abscess or boil ( Lev 13:18.; Kg2 20:7). אבעבּעת, from בּוּע, to spring up, swell up, signifies blisters, φλυκτίδες (lxx), pustulae. The natural substratum of this plague is discovered by most commentators in the so-called Nile-blisters, which come out in innumerable little pimples upon the scarlet-coloured skin, and change in a short space of time into small, round, and thickly-crowded blisters. This is called by the Egyptians Hamm el Nil, or the heat of the inundation. According to Dr. Bilharz, it…”
