Why should you be as stubborn as the Egyptians and their Pharaoh were? After he toyed with the Egyptians, didn’t they send the Israelites on their way?
So Moses and Aaron went to Pharaoh and said to him, “This is what the Lord God of the Hebrews says: How long will you refuse to humble yourself in my presence? Let my people go to worship me.
I am making the Egyptians so stubborn that they will follow the Israelites. I will receive honor because of what I will do to Pharaoh, his entire army, his chariots, and cavalry.
The Lord said to Moses, “When you get back to Egypt, see that you show Pharaoh all the amazing things that I have given you the power to do. But I will make him stubborn so that he will not let the people go.
Since you are stubborn and don’t want to change the way you think and act, you are adding to the anger that God will have against you on that day when God vents his anger. At that time God will reveal that his decisions are fair.
