I also established my covenant with them to give them the land of Canaan, the land in which they lived as sojourners. Moreover, I have heard the groaning of the people of Israel whom the Egyptians hold as slaves, and I have remembered my covenant.
Exodus 6:4-5 ESV

The land of #israel belonged to Israel before Israel was even a people. God never forgets a covenant. When Israel cries out to God, He refocuses on His covenant with them.
