Exodus 5:22-6:9 NASB
22 Then Moses returned to the Lord and said, "O Lord, why have You brought harm to this people? Why did You ever send me? 23 Ever since I came to Pharaoh to speak in Your name, he has done harm to this people, and You have not delivered Your people at all."
1 Then the Lord said to Moses, "Now you shall see what I will do to Pharaoh; for under compulsion he will let them go, and under compulsion he will drive them out of his land." 2 God spoke further to Moses and said to him, "I am the Lord; 3 and I appeared to Abraham, Isaac, and Jacob, as God Almighty, but by My name, Lord, I did not make Myself known to them. 4 I also established My covenant with them, to give them the land of Canaan, the land in which they sojourned. 5 Furthermore I have heard the groaning of the sons of Israel, because the Egyptians are holding them in bondage, and I have remembered My covenant. 6 Say, therefore, to the sons of Israel, 'I am the Lord, and I will bring you out from under the burdens of the Egyptians, and I will deliver you from their bondage. I will also redeem you with an outstretched arm and with great judgments. 7 Then I will take you for My people, and I will be your God; and you shall know that I am the Lord your God, who brought you out from under the burdens of the Egyptians. 8 I will bring you to the land which I swore to give to Abraham, Isaac, and Jacob, and I will give it to you for a possession; I am the Lord.'" 9 So Moses spoke thus to the sons of Israel, but they did not listen to Moses on account of their despondency and cruel bondage.
