Death to the Pharaoh’s Son

Then the LORD reminded him [Moses], “When you arrive back in Egypt, go to Pharaoh and perform the miracles I have empowered you to do.  But I will make him stubborn so he will not let the people go.  Then you will tell him, ‘This is what the LORD says: Israel is my firstborn son.  I commanded you to let him go, so he could worship me.  But since you have refused, be warned!  I will kill your firstborn son!'” (Exodus 4:21-23 NLT)

(It doesn’t seem right that the Pharaoh’s son should be punished for something the Lord made the Pharaoh do.)
