To the Jews Egypt was a furnace in which they were being consumed—whether literally in human sacrifice, or metaphorically in the hard labour which wasted them (Deut. iv. 20). And now the brothers were commanded to fill both hands with ashes of the furnace and throw them upon the wind,[16] either to symbolise the suffering which was to be spread wide over the land, or because the ashes of human sacrifices were thus presented to their evil genius, Typhon. If this were its meaning, the irony was keen, when at the same action a feverish inflammation breaking out in blains spread over all the nation. But, apart from any such reference to their cruel idolatry, it was right that they should suffer in the flesh. When the higher nature is dead, there is no appeal so sharp and certain as to the physical sensibility. And moreover, there are other sins which have their root in the flesh besides sloth and bodily indulgence. Wrath and cruelty and pride are strangely stimulated and excited by self-indulgence. Not in vain does St. Paul describe a “mind of the flesh,” and reckon among the fruits of the flesh not only uncleanness and drunkenness, but, just as truly, strife, jealousies, wraths, factions, divisions, heresies (Col. ii. 18; Gal. v. 19, 20). From such evil tempers, stimulated by evil appetites, the slaves of Egypt had suffered bitterly; and now the avenging rod fell upon the bodies of their tyrants. And we may perhaps detect especial suffering, certainly an especial triumph to be commemorated, in the failure of the magicians even to stand before the king. It is implied that they had done so until now, and this confirms the belief that after the third plague they had not acknowledged Jehovah, but merely said in their defeat, “This is the finger of a god.” Until now Jannes and Jambres (two, to rival the two brothers) had withstood Moses, but now the contrast between the prophet and his victims writhing in their pain was too sharp for prejudice itself to overlook: their folly was “evident unto all men” (2 Tim. iii. 8, 9). But it was not destined that Pharaoh should yield even to so tremendous a coercion what he refused to moral influences; and as Jesus after His resurrection appeared not unto all the people (hiding this crowning evidence from the eyes which had in vain beheld so much), so “the Lord made strong the heart of Pharaoh, and he hearkened not unto them, as the Lord had spoken unto Moses.” In this last expression is the explicit statement that it was now that the prediction attained fulfilment, in the manner which we have discussed already. But even this strength of heart did not reach the height of attempting any reprisals upon the torturers. The sense of the supernatural was their defence: Moses was as a god unto Pharaoh, and Aaron was his prophet.
