The sixth plague concludes the second set of three plagues. As in plague 3, there is not interview with Pharaoh, no rising up early in the morning. Instead, God just tells Moses to do something, and it is done.
This plague has loads of poetic justice. The soot comes from a kiln, one used to make bricks. Moses almost certainly took soot from a kiln that the Israelite slaves had used to make bricks for the Egyptians. As John Currid says, “The furnace, then, was a symbol of the oppression of the Hebrews, the sweat and tears they were shedding to make bricks for the Egyptians. Thus the very soot made by the enslaved people was now to inflict punishment on their oppressors” (p. 196).
In addition, throwing soot into the air was something that Egyptians priests used to do (Ryken, p. 273). They did it to signify blessing. God turned it into a curse. As Ryken says, “God was making Israel’s curse a blessing and was turning Egypt’s blessing into a curse” (p. 273).
There were several gods against which this plague was directed. Amon Re (a creator god) was a god who was supposed to heal diseases. Thoth was a god of healing arts. Imhotep was the god medicine. “But the most common deity for dealing with disease was Sekhmet, whose priests formed one of the oldest medical fraternities in antiquity” (Ryken, p. 272, quoting Currid).
Ah, the poor, foolish magicians! Not only were they impotent when it came to dealing with the plague; they could not even protect themselves!
Many scholars say that the boils were a form of anthrax. Whatever they were, they were impure. In fact, such illness was usually seen as demon-possession by the Egyptians of that time. That was a distressing to them as the physical pain.
And notice that although many passages in Exodus say that Pharaoh hardened his own heart, it is also true to say that God hardened Pharaoh’s heart. There is always mystery when it comes to the intersection of divine sovereignty and human responsibility. But at the least, we can say that Pharaoh’s self-hardening was part of God’s plan in such a way that it can also be said that God hardened Pharaoh’s heart.
So, in our day, do we worship medicine? You bet we do. But as Ryken notes, Jesus Christ alone is Lord of the (B)body (p. 272).
