22 And I will sever in that day the land of Goshen, in which my people dwell, that no swarms of flies shall be there; to the end thou mayest know that I am the Lord in the midst of the earth.

23 And I will put a division between my people and thy people: to morrow shall this sign be.

I previously wondered whether the Israelites had been affected by the turning of the river to blood in the same way that the Egyptians had. And did the frogs come upon both sets of people? And the lice? Perhaps so, but now we are told that there would be a sharp divide between the people of Israel and the people of Egypt.

This is a recurring theme in the Bible, that of a divide being made between the faithful and the profane, of God’s chosen people being saved and the wicked being destroyed. We have seen it where a protection was put around Noah’s family in the form of an ark when all the world was flooded. We have seen it where heavenly messengers drew Lot’s family out to safety when Sodom and Gomorrah was bombarded. Now we see it where a clear line is made between two halves. In one land the curse runs rampant, but it is not allowed to pass over into the neighboring land.

Thus we see multiple different ways that God is able to protect His people. He can shield them in the eye of the storm, or lead them out to safety, or put up a wall that keeps the danger at bay. He can end the danger, preserve you through the danger, or get you out of the danger. One never know just how God will save him, only that God will if he prepares himself for it.
