Then He said to Abram, “Know for certain that your seed will be strangers in a land that is not theirs, and they will be enslaved and oppressed 400 years.
I will give to you and to your seed after you the land where you are an outsider —the whole land of Canaan—as an everlasting possession, and I will be their God.”
Then they said to Pharaoh, “We came to dwell temporarily in the land, since there is no pasture for the flocks that belong to your servants, for the famine is severe in the land of Canaan. So now, please let your servants live in the land of Goshen.”
and made their lives bitter with hard labor with mortar and brick, doing all sorts of work in the fields. In all their labors they worked them with cruelty.
So I promise I will bring you up out of the affliction of Egypt, into the land of the Canaanites, Hittites, Amorites, Perizzites, Hivites and Jebusites, to a land flowing with milk and honey.’
So I have come down to deliver them out of the hand of the Egyptians, to bring them up out of that land into a good and large land, a land flowing with milk and honey, into the place of the Canaanites, Hittites, Amorites, Perizzites, Hivites and Jebusites.

What I am saying is this: Torah, which came 430 years later, does not cancel the covenant previously confirmed by God, so as to make the promise ineffective.
You must remember that you were a slave in the land of Egypt, and Adonai your God brought you out from there with a mighty hand and an outstretched arm. Therefore Adonai your God commanded you to keep Yom Shabbat.
