Exodus 5:21-23

21and they said to them, “May the Lord look on you and judge, because you have made us stink in the opinion of Pharaoh and his servants, so that you have given them an excuse to kill us!”

22Moses returned to the Lord, and said, “Lord, why have you caused trouble for this people? Why did you ever send me?

23From the time I went to speak to Pharaoh in your name, he has caused trouble for this people, and you have certainly not rescued them!”
