Genesis 12:1-9 NIV
The Call of Abram
1 The Lord had said to Abram,
“Leave your country, your people and your father’s household and go to the land I will show you.
2“I will make you into a great nation
and I will bless you;
I will make your name great,
and you will be a blessing.
3I will bless those who bless you,
and whoever curses you I will curse;
and all peoples on earth
will be blessed through you.”
4 So Abram left, as the Lord had told him; and Lot went with him. Abram was seventy-five years old when he set out from Haran.
5 He took his wife Sarai, his nephew Lot, all the possessions they had accumulated and the people they had acquired in Haran, and they set out for the land of Canaan, and they arrived there.
6 Abram traveled through the land as far as the site of the great tree of Moreh at Shechem. At that time the Canaanites were in the land.
7 The Lord appeared to Abram and said, “To your offspring I will give this land.” So he built an altar there to the Lord, Who had appeared to him.
8 From there he went on toward the hills east of Bethel and pitched his tent, with Bethel on the west and Ai on the east.
There he built an altar to the Lord and called on the Name of the Lord.
9 Then Abram set out and continued toward the Negev.
Perhaps in an human form, and so it was the Son of God; for whenever there was any visible appearance of a divine Person, under the former dispensation, it seems to be always of the essential Word, that was to be incarnate, and who spoke with an articulate voice: and said, “To your offspring I will give this land”, the whole of it inhabited by Canaanites and others; and it was for this end chiefly that Abram was called out of Chaldea into Canaan, to be shown the land, and have the grant of it for his posterity.
And there he built an altar to the Lord, Who appeared to him: by way of gratitude and thankfulness for His Gracious Appearance, and for the gift of the land of Canaan to his offspring; for on this altar he no doubt offered sacrifice in a way of thanksgiving, as Noah did when he came out of the ark.
