Abraham is called from his country
Stephen begins Israel's history by repeating God's command that Abraham leave his country and kindred for the land God would show him.
And Stephen declared: “Brothers and fathers, listen to me! The God of glory appeared to our father Abraham while he was still in Mesopotamia, before he lived in Haran, and told him, ‘Leave your country and your kindred and go to the land I will show you.’ So Abraham left the land of the Chaldeans and settled in Haran. After his father died, God brought him out of that place and into this land where you are now living.
Genesis 12:1 records the LORD's command to leave country, kindred, and household for the land He would show Abram; Acts 7:2-4 quotes the country-and-kindred command and recounts Abraham's departure.
