Exodus 5:21-23

The foremen said to them, “May the LORD judge and punish you for making us stink before Pharaoh and his officials. You have put a sword into their hands, an excuse to kill us!” Then Moses went back to the LORD and protested, “Why have you brought all this trouble on your own people, Lord? Why did you send me? Ever since I came to Pharaoh as your spokesman, he has been even more brutal to your people. And you have done nothing to rescue them!”
