22Moses went back to the LORD and said, "LORD, why have you brought such trouble on this people? Why did you even send me?" 23Ever since I went to Pharaoh to speak in your name, he has only made things worse for this people. And you haven't rescued your people at all."
After Pharaoh made the Israelites' work harder, Moses turned to the LORD and asked why he had brought trouble on his people. He asked why God had sent him, since God had not yet rescued them. God answered that Moses would now see what he would do to Pharaoh.
