Acts 7:6

Then God said to Abram, “Know for certain that your seed will be sojourners in a land that is not theirs, and they will be enslaved and mistreated four hundred years.

“So now, come and I will send you to Pharaoh, and so you shall bring My people, the sons of Israel, out of Egypt.”

Now the time that the sons of Israel lived in Egypt was 430 years.

And what I am saying is this: the Law, which came 430 years later, does not invalidate a covenant previously ratified by God, so as to abolish the promise.
