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.
Pharaoh sent for Moses and Aaron and said, “Pray that the Lord will take the frogs away from me and my people. Then I will let your people go to offer sacrifices to the Lord.”
O Lord, why do you let us wander from your ways and become so stubborn that we are unable to fear you? Return for the sake of your servants. They are the tribes that belong to you.
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.
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?
