Exodus 6:6-9

“Therefore, say to the people of Israel: ‘I am the LORD. I will free you from your oppression and will rescue you from your slavery in Egypt. I will redeem you with a powerful arm and great acts of judgment. I will claim you as my own people, and I will be your God. Then you will know that I am the LORD your God who has freed you from your oppression in Egypt. I will bring you into the land I swore to give to Abraham, Isaac, and Jacob. I will give it to you as your very own possession. I am the LORD!’” So Moses told the people of Israel what the LORD had said, but they refused to listen anymore. They had become too discouraged by the brutality of their slavery.
