Exodus 2:22-25

And she bare a son, and he called his name Gershom; for he said, I have been a sojourner in a foreign land. And it came to pass in the course of those many days, that the king of Egypt died: and the children of Israel sighed by reason of the bondage, and they cried, and their cry came up unto God by reason of the bondage. And God heard their groaning, and God remembered his covenant with Abraham, with Isaac, and with Jacob. And God saw the children of Israel, and God took knowledge of them.
