This account is very straightforward. However, I think that it is interesting that:
- The NIV Study Bible notes in its commentary on these verses that the furnace from which the soot was taken may be "...a kiln used for firing bricks, the symbol of Israel's bondage" (see Exodus 1:14 and 5:7-19).
- The same commentary also notes that the plague now extends to other animals beside the ones previously affected.
Well, we know that God always acts justly, so it is not as though Pharaoh is just some type of puppet for God's use. So there must be more to this story, and there is.
If we look back at the previous five plagues,
- The plague of blood
- The plague of frogs
- The plague of gnats
- The plague of flies
- The plague on livestock,
The book of James in the New Testament says this:
In his hardened state, Pharaoh is apparently unaware that the plagues are about to get far worse.
