1. This chapter poses a chronology problem for us. If Moses was not allowed to see the king again (10:28), how, then, in 11:8 is it that Moses went out in “hot anger”? It is probably best to read the words of 11:4-8 in conjunction with 10:28. In other words, the king said he wanted to see Moses and Aaron no more, so Moses said what we read in 11:4-8, 10:29.
2. When Moses walked out the Lord made it clear again that the king would not listen. One other point on this: because the movie “The Ten Commandments” is as popular as it is (even six decades since its production), it is good to be sure that we have a proper biblical understanding. Moses knew the Lord’s ultimate judgment would be the death of Pharaoh’s son (4:23); it was not something that he learned about later (as the Moses describes).
3. Moses interaction with (and against) Pharaoh as this point is important. Already Moses had gained a reputation before the Egyptians, and whatever positive reputation the king had it was gone. Now, a final battle is in place. Not much of a battle was it! This battle, of course, was not against Moses, but against the Great King (God). It could not be said that Pharaoh did not know God (cp. 5:2) for by this time he knew Him well. Whatever “divinity” the king though he had left, it was about to be shown to him that he believed in demonic forces.
4. Moses, with much anger (because he knew this did not have to happen), leaves the presence of the king and prepares the Israelites. With three days of darkness, how could the Egyptians operate? That’s the point, they did not. The Israelites, on the other hand, had light and they were preparing to make their way to the promised land (11:1-3). Perhaps it was on the evening of the third night that the Lord brought His last plague. Already the Egyptians are dispirited beyond measure; now they are unable to move about because of the darkness, and the soon next plague.
5. Application: The Israelites had to endure much aggravation at the hand of the Egyptians, and now they are on the cusp of leaving the bondage to a home they only heard about. Unbeknownst to them, they were about to go through their greatest trial. That is the way it is, some times. We see the bright day very close at hand and we are unaware that after this bright day comes a purging.
