between my people and your people.’ That is evident in the plagues; for example, when darkness covers the land, ‘all the people of Israel had light where they lived’ (10:23). This was a judgement on Egypt, and with it, God distinguished between those who were his, and those who were not. Finally, the plagues were a means for hardening the heart of Pharaoh. This is clear, for example, in 10:1, where God says to Moses that the signs he has worked among them have resulted in Pharaoh’s further rebellion.
