Moses and Aaron went to the king and told him that the LORD God of the Hebrews had said: How long will you stubbornly refuse to obey? Release my people so they can worship me.
I will make the Egyptians so stubborn that they will go after you. Then I will be praised because of what happens to the king and his chariots and cavalry.
On the way the LORD said to Moses: When you get to Egypt, go to the king and work the miracles I have shown you. But I will make him so stubborn that he will refuse to let my people go.
But you are stubborn and refuse to turn to God. So you are making things even worse for yourselves on that day when he will show how angry he is and will judge the world with fairness.
You must encourage one another each day. And you must keep on while there is still a time that can be called “today”. If you don't, then sin may fool some of you and make you stubborn.
