Exodus 5:21-23

So they said to Moses and Aaron, “May the LORD punish you. You caused the king and his officers to hate us. You have given them an excuse to kill us.” Then Moses returned to the LORD and said, “Lord, why have you brought this trouble on your people? Is this why you sent me here? I went to the king and said what you told me to say, but ever since that time he has made the people suffer. And you have done nothing to save them.”
