Genesis 15:6-10 American Standard Version (ASV)

6. And he believed in Jehovah; and he reckoned it to him for righteousness.

7. And he said unto him, I am Jehovah that brought thee out of Ur of the Chaldees, to give thee this land to inherit it.

8. And he said, O Lord Jehovah, whereby shall I know that I shall inherit it?

9. And he said unto him, Take me a heifer three years old, and a she-goat three years old, and a ram three years old, and a turtle-dove, and a young pigeon.

10. And he took him all these, and divided them in the midst, and laid each half over against the other: but the birds divided he not.
