God's Promise to Abraham

What did God promise to Abraham?

Acts 7:5-7 God's Promise to Abraham

Acts 7:8-11 Patriarchs

ACTS 7:5 5 “And God gave him no inheritance in it, not even enough to set his foot on. But even when Abraham had no child, He promised to give it to him for a possession, and to his descendants after him.

What is the "it" that Stephen is referring to in Acts 7:5?
The "land" that God promised to Abraham: Then He said to him, "I am the Lord, who brought you out of Ur of the Chaldeans, to give you this land to inherit it" (Acts 7:4, see Haran).

ACTS 7:6-7 6 “But God spoke in this way: that his descendants would dwell in a foreign land, and that they would bring them into bondage and oppress them four hundred years. 7 ‘And the nation to whom they will be in bondage I will judge,’ said God, ‘and after that they shall come out and serve Me in this place.’

To what "foreign land" (Acts 7:6) and "nation to whom they will be in bondage" (Acts 7:7) was God referring?
Egypt, where Abraham's descendants will be oppressed as slaves for four hundred years before God uses Moses to deliver them.

When did God tell Abraham about the bondage of his descendants and His deliverance?
Then He said to Abram: "Know certainly that your descendants will be strangers in a land that is not theirs, and will serve them, and they will afflict them four hundred years. And also the nation whom they serve I will judge; afterward they shall come out with great possessions. Now as for you, you shall go to your fathers in peace; you shall be buried at a good old age. But in the fourth generation they shall return here, for the iniquity of the Amorites is not yet complete" (Genesis 15:13-16). "Then you shall say to Pharaoh, ‘Thus says the LORD: "'Israel is My son, My firstborn. So I say to you, let My son go that he may serve Me. But if you refuse to let him go, indeed I will kill your son, your firstborn.'" (Exodus 4:22-23)

With whom did Abraham seal this promise?
With both God the Father and Jesus.

Abraham met Jesus?
See Genesis 15.
