Genesis 15:5 BBE

³  And Abram said, You have given me no child, and a servant in my house will get the heritage.

⁴  Then said the Lord, This man will not get the heritage, but a son of your body will have your property after you.

⁵  And he took him out into the open air, and said to him, Let your eyes be lifted to heaven, and see if the stars may be numbered; even so will your seed be.

⁶  And he had faith in the Lord, and it was put to his account as righteousness.

⁷  And he said to him, I am the Lord, who took you from Ur of the Chaldees, to give you this land for your heritage.
