Exodus 5:20-23

They met Moses and Aaron, who were waiting for them, as they came out from Pharaoh; and they said to them, “The LORD look on you and judge, because you have made us stink in the sight of Pharaoh and his servants, and have put a sword in their hand to kill us.” Then Moses turned to the LORD and said, “O Lord, why have you done evil to this people? Why did you ever send me? For since I came to Pharaoh to speak in your name, he has done evil to this people, and you have not delivered your people at all.”
