Cross-reference
Genesis 26:5 cites Abraham's obedience as grounds for God's covenant blessing to Isaac. Abram's immediate departure here is a defining example of that obedience.
Genesis 11:31 says Terah took Abram from Ur. It provides earlier context for the family's journey mentioned here.
Genesis 11:27 establishes Abram's family tree. It's the necessary background for his departure noted in 12:4.
Genesis 25:7 records Abraham's age at death (175). Paired with his age at departure (75) here, these bracket Abraham's 100 years in Canaan — two bookend biographical markers.
Hebrews 11:8 directly highlights Abram's obedient faith in leaving, as described in this verse.
Acts 7:4 directly recounts Abram leaving the Chaldeans and then Haran — Stephen retelling this exact event in his speech before the Sanhedrin.
